More TSO4 fixes, from the freebsd driver:
- the chip doens't want the lenght of options, but the complete lenght of
  ip headers (ip + tcp + options). Fix this for the BGE_IS_5717_PLUS()
  and BGE_IS_5705_PLUS() cases; FreeBSD doens't cover the last case so
  leave it as is for now. This fixes checksum failures for heavy transfers.
- It looks like the transmit engine hangs if the TCP segment crosses a 4GB
  boundary. FreeBSD fixes it by mapping everything below 4GB; instead
  try detect when this happens and do the bounce only when needed.

With these fixes I could transfers 3GB images over ftp at gigabit speed
(112MB/s with wget) without problems. Tested on a

Don't destroy the dma maps if we're not disabling the adapter, avoids
a KASSERT() when bus_dmamap_destroy() is called from interrupt
context via bge_watchdog()

Set IFF_OACTIVE only when bge_encap() fails on adapter ressource shortage.
Otherwise we may set IFF_OACTIVE while no transmit is in progress, and
nothing will clear it.

If bus_dmamap_load_mbuf() fails with EFBIG, m_defrag() the chain and retry.
Refine the check for the 4GB boundary workaround (a fragment should also
not cross the boundary), and do it only for TSO.

If bge_encap() fails and didn't set IFF_OACTIVE, drop the packet.

Bring in more hardware bug workarounds from freebsd.

With these it seems that a BCM5720 A0 can survive a few hours of internet
load with TSO4 enabled.

Sync bge(4) up to if_bge.c rev. 1.287. Sync brgphy(4) up to 1.74.
Fix some bugs on bnx(4).

Common:
- Add device IDs for Broadcom BCM57710, BCM57711(E), BCM57712(E) and
  BCM57766 (pcidevs only).
- Fix BCM5709 PHY detection.
- Fix detection of BGEPHYF_FIBER_{MII|TBI}
- Add BCM5708S support in brgphy(4).
- Don't use the WIRESPEED function for fiber devices.
bge(4):
- Add some Fujitsu's device support from Michael Moll.
- Add BCM57762 support (PR#46961 from Ryo Onodera).
- Add Altima AC1003, APPLE BCM5701, Broadcom BCM5785F. BCM5785G,
  BCM5787F, BCM5719, BCM5720, BCM57766, BCM57782 and BCM57786.
- Fix DMA setting for read/write on conventional PCI bus devices.
  This bug was added in rev. 1.166.
- Fix printing "discarding oversize frame (len=-4)" message and
  crash by NULL pointer dereferencing.
- The BCM5785 is a PCIe chip but does not report PCIe capabilities.
  Check for this chip explicitely and enable PCIe. Fixes
  'firmware handshake timeout'.
- Allow disabling interrupt mitigation.
- Workaround for BCM5906 silicon bug. When auto-negotiation results
  in half-duplex operation, excess collision on the ethernet link may
  cause internal chip delays that may result in subsequent valid
  frames being dropped due to insufficient receive buffer resources.
  (FreeBSD: r214219, r214251, r214292).
- Allow write DMA to request larger DMA burst size to get better
  performance on BCM5785. (FreeBSD r213333: OpenBSD 1.294)
- Enable TX MAC state machine lockup fix for both BCM5755 or higher
  and BCM5906. Publicly available data sheet just says it may happen
  due to corrupted TxMbuf. (FreeBSD r214216)
- Follow Broadcom datasheet:
  Delay 100 microseconds after enabling transmit MAC.
  Delay 10 microseconds after enabling receive MAC. (FreeBSD
  r241220)
- Insert the completion barrier between register write and the
  consecutive delay(). It will fix some device timeout problems we have
  seen before.
- Add DELAY(40) after turning on write DMA state machine.
- Add some workarounds for 5717 A0 and 5776[56] to be stable.
- Check BGE_RXBDFLAG_IPV6 flag for 5717_PLUS case. Note that
  {tcp,udp}6csum flag is currently not added in the capability.
- Add delay after clearing BGE_MACMODE_TBI_SEND_CFGS for the link
  checking.
- Do not touch the jumbo replenish threshold register on chips that do
  not have jumbo support.
- Wait for the bootcode to complete initialization for 5717 and newer
  devices.
- 5718 and 57785 document say we should wait 100us in init.
- Fix a bug that chips which have BCM5906 ASIC touch GPIO wrongly.
- Fix the setting of Tx Random Backoff Register.
- Check the hardware config words and print them.
- Set BGE_MISC_CTL's byte/word swap options before using
  bge_readmem_ind(). Fixes PR#47716.
- For BGE_IS_575X_PLUS() devices, don't set
  BGE_RXLPSTATCONTROL_DACK_FIX bits because these bits are reserved.
- Document says 5717 and newer chips have no
  BGE_PCISTATE_INTR_NOT_ACTIVE bit, so don't use the bit on those
  chips. Same as OpenBSD.
- Fix a bug that the PHY address bits in MI_MODE register is wrongly
  cleard. Set the PHY address correctly.
- Use BGE_SETBIT() instead of CSR_WRITE_4() for the BGE_MISC_LOCAL_CTL
  register to not to modify some GPIO bits.
- Set DMA watermark depend on the PCI max payload size.
- Set BGE_JUMBO_CAPABLE correctly.
- Fix a link detect bug on non-autopoll systems.
- Change the TX ring size for 5717 series and 57764 series.
- Set maximum read byte count to 2048 for PCI-X BCM5703/5704 devices.
- For PCI-X BCM5704, set maximum outstanding split transactions to 0.
- Add 40bit DMA bug workaround(BGEF_40BIT_BUG) from FreeBSD.
  This workaround is for 5714/5715 controllers and is not actually a
  MAC controller bug but an issue with the embedded PCIe to PCI-X
  bridge in the device. This change uses bus_dmatag_subregion(),
  so this workaround won't work on some archs which doesn't support
  bus_dmatag_subregion().
- Add 2500SX support (not tested).
- Don't use the PHY Auto Poll Mode on many chips. This fixes a bug
  that MII Fiber NIC drop packet about 50%. Tested on HP Moonshot.
- Add workaround for PR#48451. Some BCM5717-5720 based systems getNMI
  on boot. This problem doesn't occur when we don't use prefetchable
  memory in the APE area. Tested with HP MicroServer Gen8.
- In the BCM5703, the DMA read watermark should be set to less than
  or equal to the maximum memory read byte count of the PCI-X command
  register.
- Fix a bug that BGE_PHY_TEST_CTRL_REG isn't set correctly on some
  PCIe devices.
- Use another firmware command in bge_asf_driver_up(). Same as Linux.
  This change fixes a bug that watchdog timeout occurs every 25-30
  minutes on HP ML110 G6 reported enami@ in PR#49657.
- Fix mbuf leak on failure.
- Remove PCI_PRODUCT_BROADCOM_BCM5724 and
  PCI_PRODUCT_BROADCOM_BCM5750M. These devices have not released to
  public.
- Add some workaround code for BGE_ASICREV_BCM5784 from Linux.
- Change some printf() to aprint_*().
- Fix typo in comments.
- Cleanup.
brgphy(4):
- Fix bit definition of BRGPHY_MRBE_MSG_PG5_NP_T2 from FreeBSD.
- Add BCM5481, BCM5709S, BCM5756, BCM5717C, BCM5720C, BCM5785,
  BCM57765(PR#46961), BCM57780
- In brgphyattach(), set sc_isbge, sc_isbnx and sc_phyflags before
  PHY_RESET() because brgphy_reset() refers those flags.
- Call brgpy specific autonego function in MII_TICK. Before this
  commit, only MII_MEDIACHG calls brgphy_mii_phy_auto() and MII_TICK
  calls MI mii_phy_auto(). That was not intended.
- Remove extra delay in brgphy_mii_phy_auto. Same as {Free,Open}BSD.
bnx(4):
- Add missing ifmedia_delete_instance() in bnx_detach().
- Fix a bug that BNX_NO_WOL_FLAG isn't correctly set on some chips.
  Reported by From Henning Petersen in PR#44151.
- Fix SERDES initialization.
- Get out of the interrupt handler early if !IFF_RUNNING.

- Add MSI support.
- Use tagged status function for 5717 and newer devices. All controllers
  except BCM5700 support tagged status but we use tagged status only for MSI
  case on BCM5717. Otherwise MSI on BCM5717 does not work. Same as other *BSDs.

	- brgphy(4): Add BCM5756, BCM5717C, BCM5719C, BCM5720C and BCM57780.
	- Add some bugfixes and enhancement from FreeBSD:
	  - Workaround for BCM5906 silicon bug. When auto-negotiation results in
	   half-duplex operation, excess collision on the ethernet link may
	   cause internal chip delays that may result in subsequent valid

	  From Linux tg3 driver.
	- Sync with *BSD. No functional change:
	  - make bge_chipid() and use it.
	  - use switch() instead of a lot of if()s.
	- Check BGE_RXBDFLAG_IPV6 flag for 5717_PLUS case.
	  Note that {tcp,udp}6csum flag is currently not added in the
	  capability.
	- Add delay after clearing BGE_MACMODE_TBI_SEND_CFGS for the link
	  checking.  FreeBSD has the same delay().
	- Rename PHY related flags for the consistency. It's the same as
	  FreeBSD.
	- Remove BGE_10_100_ONLY flag because this was not used.
	  For 10/100 devices, when calling mii_attach(), mask BMSR_EXTSTAT
	  flag to not to check Gigabit flags. It's the same as FreeBSD.
	- In brgphyattach(), set sc_isbge, sc_isbnx and sc_phyflags before
	  PHY_RESET() because brgphy_reset() refers those flags.
	- Call brgpy specific autonego function in MII_TICK. Before this commit,
	  only MII_MEDIACHG calls brgphy_mii_phy_auto() and MII_TICK calls MI
	  mii_phy_auto(). That was not intended.
	- Sync with FreeBSD and OpenBSD. Almost the same as OpenBSD rev. 1.325:
	  - Sync the ring setup code closer to FreeBSD's driver
	  - Do not touch the jumbo replenish threshold register on chips that
	    do not have jumbo support
	- Wait for the bootcode to complete initialization for 5717 and newer
	  devices.  See BCM5718 programmer's guide's "step 13,
	  Device reset Procedure, Section7".
	  57781's document has the same note.
	- 5718 and 57785 document say we should wait 100us.
	- Change the order of register settings a little to match both
	  Broadcom's document and Linux tg3.
	- Add detach function.
	- Fix a bug that chips which have BCM5906 ASIC touch GPIO wrongly.
	- Fix a bug that the NVRAM lock timeout occured on sparc64 onboard bge.
	- Check BGE_SGDIG_STS when the chip is NOT a 5717 A0, like freebsd
	  (OpenBSD rev. 1.327).
	- Fix the setting of Tx Random Backoff Register.
	- Add BGE_PCIMISCCTL_PCISTATE_RW in BGE_INIT. It's required to set the
	  PCISTATE register correctly.
	- Update comments from 57XX-PG105-R.pdf and 5718-PG106-R.pdf.
	- Add missing bus_dmamap_sync() in bge_intr(). The status word is
	  in DMAed area. Same as other *BSDs.
	- Check the hardware config words and print them. This change only
	  read them and print the values.
	- Set BGE_MISC_CTL's byte/word swap options before using
	  bge_readmem_ind().
	- For BGE_IS_575X_PLUS() devices, don't set
	  BGE_RXLPSTATCONTROL_DACK_FIX bits because these bits are reserved.
	- bge_init_tx_ring() uses BGE_RSLOTS (==256) but bge_free_tx_ring() uses
	  BGE_TX_RING_CNT (== 512). Delete BGE_RSLOTS and use BGE_TX_RING_CNT.
	  Same as OpenBSD's if_bge.c rev. 1.86.
	- Document says 5717 and newer chips have no
	  BGE_PCISTATE_INTR_NOT_ACTIVE bit, so don't use the bit on those
	  chips. Same as OpenBSD.

- Sync with FreeBSD and OpenBSD. Almost the same as OpenBSD rev. 1.325:
 - Sync the ring setup code closer to FreeBSD's driver
 - Do not touch the jumbo replenish threshold register on chips that do not
   have jumbo support
 - Add/sync some of the comments
- Use macro.
- Remove unused code.

- Rename PHY related flags for the consistency. It's the same as FreeBSD.
- Remove BGE_10_100_ONLY flag because this was not used.
  For 10/100 devices, when calling mii_attach(), mask BMSR_EXTSTAT flag to

Fix three bugs:
- An workaround for TX data corruption is only for 5719 "A0".
  Fix the wrong evaluation.
- Check BGE_RXBDFLAG_IPV6 flag for 5717_PLUS case.
  Note that {tcp,udp}6csum flag is currently not added in the capability.

- Workaround for BCM5906 silicon bug. When auto-negotiation results in
 half-duplex operation, excess collision on the ethernet link may cause
 internal chip delays that may result in subsequent valid frames being
 dropped due to insufficient receive buffer resources.
 (FreeBSD: r214219, r214251, r214292)

- Allow write DMA to request larger DMA burst size to get better
 performance on BCM5785.
 (FreeBSD r213333: OpenBSD 1.294)

- Enable TX MAC state machine lockup fix for both BCM5755 or higher

Extend device API by device_power_private and device_power_set_private.
The latter is a temporary mean until the pnp_register API itself is
overhault. This functions allow a generic power handler to store its
state independent of the driver.

Use this and revamp the PCI power handling. Pretty much all PCI devices
had power handlers that did the same thing, generalize this in
pci_generic_power_register/deregister and the handler. This interface
offers callbacks for the drivers to save and restore state on
transistions. After a long discussion with jmcneill@ it was considered
to be powerful enough until evidence is shown that devices can handle
D1/D2 with less code and higher speed than without the full
save/restore. The generic code is carefully written to handle device
without PCI-PM support and ensure that the correct registers are written
to when D3 loses all state.

Reimplement the generic PCI network device handling on
top of PCI generic power handling.

Introduce pci_disable_retry as used and implemented locally at least by
ath(4) and iwi(4). Use it in this drivers to restore behaviour from
before the introduction of generic PCI network handling.

Convert all PCI drivers that were using pnp_register to the new
framework. The only exception is vga(4) as it is commonly used as
console device. Add a note therein that this should be fixed later.

Convert bge(4) to device/softc separation. Use aprint_* instead of
printf all over the place. Only the debug macros are kept. Place the TSO
message about the hard case under debug.

PR/33828: Pawel Chwalowski: Add support for Broadcom BCM5789 chip

sync with head.

Change "inline" back to "__inline" in .h files -- C99 is still too
new, and some apps compile things in C89 mode. C89 keywords stay.

As per core@.

Remove leading __ from __(const|inline|signed|volatile) -- it is obsolete.

Add support for bcm5714 and (possibly incorrect) support for the
bcm5715 PCI-Express dual-port NICs. Taken from the Broadcom-supplied
Linux driver, bcm-8.3.13a.

Add nascent support for the bcm5780, but (since I have no bcm5780 to
test), don't yet add an entry which allows us to match or attach to a
5780.

Change 5752 support: Follow the lead of the Broadcom-supplied Linux
driver (bcm) and the Linux tg3 driver, and treat the 5752 like a 5750.

Add PCI device-ids to sys/dev/pci/pcidevs for newer Broadcom gigabit
ethernet devices: bcm5714, bcm5752 (previously the 5789, but fvdl
committed that whilst I was musing).

Add definitions to sys/dev/pci/if_bgereg.h for the Broadcom 57xx-family
ASIC revisions on these newer chips.

Add entries to the PCI-device-version and bge-internal-asic-revision
tables in sys/dev/pci/if_bge.c to use these new devices. Pending
further information, follow the lead of FreeBSD's if_bge.c driver and,
pending further info, treat these new chips as we do the 5750.

Remove unnecessary byteswap code so that bge(4) should work
at least on macppc.

Add TSO support to bge(4) for PCI-Express bge devices, which are
shipped from the factory with TSO-capable firmware.  The TSO support
here may also work on 5705 chips, but that is (so far) untested.

TSO support written after careful reading of the Linux tg3 driver,
and (after attempting to deconstruct the cut-and-paste mess therein)
very close reading of the Broadcom-supplied Linux driver, particularly
the building of Tx-DMA buffer descriptors (bds). The TSO code herein was
then rewritten from scratch, circa 4am local time, October 27 2005.
(In other words: this is 4am software; caveat emptor.)

Other magic register settings in this patch are required; without
them, attepmting to use TSO locks up the chip. The required register
settings were extracted from the cited Linux drivers.

Note that TSO-capable firmware for the 5703/5704 is distributed in
non-GPL form with the aforementioned Linux drivers. Once the 5705 case
is debugged, (particularly the pseudo-header checksum precalculation
flagged with an XXX) downloading that TSO-capable firmware to the
5703/5704 should, in principle, enable TSO support on all but the
original bcm5700 (I forget if the 5701 can support TSO, or not).

Note also that the ``hard case '' of IP/TCP headers spanning more than
one mbuf is not handled; I haven't been able to trigger it.  In any
case, since TSO applies only to packets generated by the local TCP,
and our TCP always leaves space for TCP headers and a normal IP
header, TSO on an IP/TCP header spanning multiple headers can only
arise due to insertion of IP options. I beleive that we are clearly
better off outlawing that case, and requiring ip_insertoptions()
to  pull-up TCP headers on any packets with M_CSUM_TSOv4 set.

As far as I know, bge hardwar does not support TSO for IPv6.

Correct a performance bug from Bill Paul's original FreeBSD bge(4) driver:
Each call to the FreeBSD bge_start() routine the transmit producer
pointer index from the chip mailbox register BGE_MBX_TX_HOST_PROD0_LO.
The local copy of that value is then updated by bge_encap() as
bge_encap() encapsulates packets in the Tx ring. If bge_encap()
succeds in encpuslating one or more packets, bge_start() tells the
chip to start sending the newly-encinitiates writes the new value back
to the chip mailbox register.
However, comparison of the Linux drivers (Broadcom-supplied and
open-source tg3.c) and to the OpenSolaris driver confirms that
register BGE_MBX_TX_HOST_PROD0_LO is write-only to software.
Thus, we can just keep a copy in the softc, and eliminate the
(expensive) PCI register write on each call to bge_start().
``Make it so''.

Add 802.3x flow control support.  From HITOSHI Osada.

Possibloe fix for some bge chip revisions taking a long time to reset
(e.g., polling for a half-second or more at splnet(), blocking most
interrupts, durin an ifconfig down/ifconfig up).

Appears to help for a 5704C rev A3, which is the only chip I've
ever seen that had even a mild version of the reported problem.

Add hooks to dynamically change the bge Rx interrupt thresholds.  I
found empiricaly that (at least on bcm5700s) the Rx coalesce and bd
counts cannot be updated on-the-fly; attempting to do so (even at
splhigh()) causes weird behaviour.

Instead, add a softc flag to record that the desired softc values for
Rx-interrupt thresholds have changed; check that boolean in the interrupt
routine. If set, apply the new values there and clear the flag.

Add some extra register definitions from FreeBSD and Linux:
BGE_MISC_TIMER register definition, and more bit definitions for
HCC-mode. (I would credit individuals, but the attributions are buried
deep in my own tree.)

Match 5703 ASIC A3.

Also, when printing the ASIC ID, print the revision in hex in all
cases to avoid extra confusion if only the "superclass" of the ASIC
is recognized.

* match more cards (from FreeBSD)
* don't set the NOCRC bit in the mode control register, it can cause
  problems on some chips (from the broadcom errata via FreeBSD)
* implement a fallback quirktable that is searched only using the
  major asic revision, so that the driver has a shot at supporting
  newer versions properly without modification
* rename asicrev -> chipid, like the FreeBSD driver

Add newer 5704 asic revs, and add them to the table, with the
BGE_QUIRK_ONLY_PHY_1 quirk in their entry.

Commit workaround for hardware bug: 5701 chips running in PCI-X mode
require that the DMA receive buffers be aligned. The driver was
deliberately mis-aligning by 2 bytes, to force the layer-2/3
headers to 32-bit alignment.

Workaround: if chip is a 5701, and is in PCI-X mode, leave the DMA
buffers aligned.  If the host CPU requires alignment, copy the buffer
after reception to force aligment.

Tested  on an i386 in  PCI-X bus, with __NO_STRICT_ALIGNMENT forced off.
