bge(4): fix the MP improvements and improve some more.

- Have two locks sc_core_lock at IPL_NONE and sc_intr_lock at IPL_NET and
  use appropriately.

- Use stopping flags instead of bge_if_flags so that bge_if_flags only
  needs to be protected by the sc_core_lock

- Use ifmedia_init_with_lock and provide the sc_intr_lock. mii operatiions
  are done from the interrupt handler.

- Fixup locking in bge_detach.

- Rename bge_watchdog to bge_watchdog_tick to avoid confusion with the
  if_watchdog method.

- Sprinkle some more asserts.

Whitespace - mostly align the line continutation characters

Convert bge_pending_rxintr_change to a bool (from int)

G/C unused softc members

Make bge_detaching a bool. NFC.

softc member naming consistency with wm(4). (Taylor made me do it... not
really)

bge: Mirror the bus_dma RX buffer changes in the OpenBSD driver

This change reduces the amount of work done in the interrupt handler.

Make bge(4) MP safe

This started out as a fix so that LOCKDEBUG wouldn't explode with kernel
lock spinout.  LOCKDEBUG is too aggressive now and really should be
relaxed.

Whitespace

Provide and use (when appropriate) a bge_free_jumbo_mem.

Some more BITS(3)

G/C the unused bge_rx_mini_chain member from bge_chain_data. It was removed
from the FreeBSD driver in 2003.

Sprinkle some BITS(3).  Same code before and after.

Use BUS_ADDR_{LO,HI}32. NFCI.

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.

Include <sys/rndsource.h> where it is actually used.

I had removed <sys/rnd.h> from files that didn't mention anything of
the rnd(9) API.  But they included other files which assumed
<sys/rnd.h> had already been included.

1) Move core entropy-pool code and source/sink/sample management code
   to sys/kern from sys/dev.

2) Remove use of NRND as test for presence of entropy-pool code throughout
   source tree.

3) Remove use of RND_ENABLED in device drivers as microoptimization to
   avoid expensive operations on disabled entropy sources; make the
   rnd_add calls do this directly so all callers benefit.

4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might
   have lead to slight entropy overestimation for some sources.

5) Add new source types for environmental sensors, power sensors, VM
   system events, and skew between clocks, with a sample implementation
   for each.

ok releng to go in before the branch due to the difficulty of later
pullup (widespread #ifdef removal and moved files).  Tested with release
builds on amd64 and evbarm and live testing on amd64.

First step of random number subsystem rework described in
<20111022023242.BA26F14A158@mail.netbsd.org>.  This change includes
the following:

	An initial cleanup and minor reorganization of the entropy pool
	code in sys/dev/rnd.c and sys/dev/rndpool.c.  Several bugs are
	fixed.  Some effort is made to accumulate entropy more quickly at
	boot time.

	A generic interface, "rndsink", is added, for stream generators to
	request that they be re-keyed with good quality entropy from the pool
	as soon as it is available.

	The arc4random()/arc4randbytes() implementation in libkern is
	adjusted to use the rndsink interface for rekeying, which helps
	address the problem of low-quality keys at boot time.

	An implementation of the FIPS 140-2 statistical tests for random
	number generator quality is provided (libkern/rngtest.c).  This
	is based on Greg Rose's implementation from Qualcomm.

	A new random stream generator, nist_ctr_drbg, is provided.  It is
	based on an implementation of the NIST SP800-90 CTR_DRBG by
	Henric Jungheim.  This generator users AES in a modified counter
	mode to generate a backtracking-resistant random stream.

	An abstraction layer, "cprng", is provided for in-kernel consumers
	of randomness.  The arc4random/arc4randbytes API is deprecated for
	in-kernel use.  It is replaced by "cprng_strong".  The current
	cprng_fast implementation wraps the existing arc4random
	implementation.  The current cprng_strong implementation wraps the
	new CTR_DRBG implementation.  Both interfaces are rekeyed from
	the entropy pool automatically at intervals justifiable from best
	current cryptographic practice.

	In some quick tests, cprng_fast() is about the same speed as
	the old arc4randbytes(), and cprng_strong() is about 20% faster
	than rnd_extract_data().  Performance is expected to improve.

	The AES code in src/crypto/rijndael is no longer an optional
	kernel component, as it is required by cprng_strong, which is
	not an optional kernel component.

	The entropy pool output is subjected to the rngtest tests at
	startup time; if it fails, the system will reboot.  There is
	approximately a 3/10000 chance of a false positive from these
	tests.  Entropy pool _input_ from hardware random numbers is
	subjected to the rngtest tests at attach time, as well as the
	FIPS continuous-output test, to detect bad or stuck hardware
	RNGs; if any are detected, they are detached, but the system
	continues to run.

	A problem with rndctl(8) is fixed -- datastructures with
	pointers in arrays are no longer passed to userspace (this
	was not a security problem, but rather a major issue for
	compat32).  A new kernel will require a new rndctl.

	The sysctl kern.arandom() and kern.urandom() nodes are hooked
	up to the new generators, but the /dev/*random pseudodevices
	are not, yet.

	Manual pages for the new kernel interfaces are forthcoming.
