sys: Drop redundant NULL check before m_freem(9)

m_freem(9) safely has accepted NULL argument at least since 4.2BSD:
https://www.tuhs.org/cgi-bin/utree.pl?file=4.2BSD/usr/src/sys/sys/uipc_mbuf.c

Compile-tested on amd64/ALL.

Suggested by knakahara@

if_stats(9): Add ifp argument to if_stat..._ref.

This will enable us to pass the ifp through to a dtrace probe inside.

No functional change intended in this change, but this is an API
change visible to modules so it shouldn't be pulled up.

Remove unnecessary include of <sys/malloc.h>.

Explicitly cast a __MASK(40) to bus_addr_t (for 32bit bus_addr_t archs)

Ensure bus_dmatag_subregion is called with an inclusive max_addr
everywhere.

prop_data_data_nocopy -> prop_data_value

Mostly merge changes from HEAD upto 20200411

Don't bother with IFF_OACTIVE.

Support MBUFTRACE.

If bus_dmatag_subregion(), actually fall back on the base 64-bit
DMA tag.

Duh, acctually use all 64-bits when giving the rings to the chip.

Add explicit casts in bus_dmatag_subregion() calls to avoid overflow /
truncation warnings on 32-bit platforms.

Harmonize bus_dmatag_subregion() handling with other drivers.

Use the 64-bit PCI DMA tag if it's available, but range-limit to
40-bit because that's what the hardware can do.

 Use ETHER_LOCK()/ETHER_UNLOCK() for all ethernet drivers to protect ec_multi*.

No functional change:
 - Simplify MII structure initialization and reference.
 - u_int*_t -> uint*_t.
 - KNF

Sync with HEAD

 Change MII PHY read/write API from:

	int (*mii_readreg_t)(device_t, int, int);
	void (*mii_writereg_t)(device_t, int, int, int);
to:

	int (*mii_readreg_t)(device_t, int, int, uint16_t *);
	int (*mii_writereg_t)(device_t, int, int, uint16_t);

Now we can test if a read/write operation failed or not by the return value.

 In 802.3 spec says that the PHY shall not respond to read/write transaction
to the unimplemented register(22.2.4.3). Detecting timeout can be used to
check whether a register is implemented or not (if the register conforms to
the spec). ukphy(4) can be used this for MII_MMDACR and MII_MMDAADR.

 Note that I noticed that the following code do infinite loop in the
read/wirte function. If it accesses unimplemented PHY register, it will hang.
It should be fixed:

tag issues.)

Move bpf_mtap and if_ipackets++ on Rx of each driver to percpuq if_input

The benefits of the change are:
- We can reduce codes
- We can provide the same behavior between drivers
  - Where/When if_ipackets is counted up
  - Note that some drivers still update packet statistics in their own
    way (periodical update)
- Moved bpf_mtap run in softint
  - This makes it easy to MP-ify bpf

Proposed on tech-kern and tech-net

Apply deferred if_start framework

if_schedule_deferred_start checks if the if_snd queue contains packets,
so drivers don't need to check it by themselves.

KNF. Remove extra spaces. No functional change.

Introduce m_set_rcvif and m_reset_rcvif

The API is used to set (or reset) a received interface of a mbuf.
They are counterpart of m_get_rcvif, which will come in another
commit, hide internal of rcvif operation, and reduce the diff of
the upcoming change.

No functional change.

Sync with HEAD

Introduce softint-based if_input

This change intends to run the whole network stack in softint context
(or normal LWP), not hardware interrupt context. Note that the work is
still incomplete by this change; to that end, we also have to softint-ify
if_link_state_change (and bpf) which can still run in hardware interrupt.

This change softint-ifies at ifp->if_input that is called from
each device driver (and ieee80211_input) to ensure Layer 2 runs
in softint (e.g., ether_input and bridge_input). To this end,
we provide a framework (called percpuq) that utlizes softint(9)
and percpu ifqueues. With this patch, rxintr of most drivers just
queues received packets and schedules a softint, and the softint
dequeues packets and does rest packet processing.

To minimize changes to each driver, percpuq is allocated in struct
ifnet for now and that is initialized by default (in if_attach).
We probably have to move percpuq to softc of each driver, but it's
future work. At this point, only wm(4) has percpuq in its softc
as a reference implementation.

Additional information including performance numbers can be found
in the thread at tech-kern@ and tech-net@:

Use pci_aprint_devinfo(9) instead of pci_devinfo+aprint_{normal,naive}
where it looks straightforward, and pci_aprint_devinfo_fancy in a few
others where drivers want to supply their own device names instead
of the pcidevs generated one. More complicated cases, where names
are composed at runtime, are left alone for now. It certainly makes
sense to simplify the drivers here rather than inventing a catch-all API.
This should serve as as example for new drivers, and also ensure
consistent output in the AB_QUIET ("boot -q") case. Also, it avoids
excessive stack usage where drivers attach child devices because the
buffer for the device name is not kept on the local stack anymore.

When shutting down the network interface it is not enough to stop it. Some

Redefine bpf linkage through an always present op vector, i.e.
#if NBPFILTER is no longer required in the client.  This change
doesn't yet add support for loading bpf as a module, since drivers
can register before bpf is attached.  However, callers of bpf can
now be modularized.

Dynamically loadable bpf could probably be done fairly easily with
coordination from the stub driver and the real driver by registering
attachments in the stub before the real driver is loaded and doing
a handoff.  ... and I'm not going to ponder the depths of unload
here.

Tested with i386/MONOLITHIC, modified MONOLITHIC without bpf and rump.

Prepare for PMF self-suspension: in the if_stop() methods, clear
IFF_UP and IFF_RUNNING before running the 'disable' step, instead
of after.  Soon I will handle the 'disable' step by calling into

This change lets the if_stop() routines exit early when they find
on entry that IFF_RUNNING is not set.

Start patching up the kernel so that a network driver always has
the opportunity to handle an ioctl before generic ifioctl handling
occurs.  This will ease extending the kernel and sharing of code
between drivers.

First steps:  Make the signature of ifioctl_common() match struct
ifinet->if_ioctl.  Convert SIOCSIFCAP and SIOCSIFMTU to the new
ifioctl() regime, throughout the kernel.

Make many ethernet drivers share the common code for MII media

This patch shrinks the source code size by 979 lines.  There was

PR/29925: Mihai CHELARU: Fix for stge 1023.

Pull up revision 1.28 (requested by bouyer in ticket #2062):
Write the station address using 8-bits writes instead of 16-bits.
This is what the linux driver does, and makes the DGE-550T work without the
STGE_CU_BUG hack. So remove the STGE_CU_BUG hack.
Set bit 0x0020 in STGE_DebugCtrl too, the linux driver does it (the comments
note this as a workaround, without more details. This doesn't seem to make
things worse).
Also initialize STGE_RxDMABurstThresh and STGE_RxDMAUrgentThresh, using
values from the linux driver.
Approved by Jason Thorpe.

Put in code that, if enabled, makes *my* copper Sundance TI cards work-
promiscuous mode is needed for this for now. The default is to have this
