SGMII in-band autonegotiation was previously kept untouched (and restored
after switching back from 2500Base-X to SGMII). Now that the kernel offers
a way to announce in-band capabilities and nable/disable in-band AN,
implement the .inband_caps and .config_inband driver ops.
This moves the responsibility to configure SGMII in-band AN from the PHY
driver to phylink.

Recent version of tcpdump (tcpdump-4.99.6-1.fc43.x86_64) seems to have
removed the spurious space after msg type in PTP info, e.g.:
before: PTPv2, majorSdoId: 0x0, msg type : sync msg, length: 44
after: PTPv2, majorSdoId: 0x0, msg type: sync msg, length: 44
Update our patterns to match both.

The gro.py test (testing software GRO) is slightly flaky when
running against fbnic. We see one flake per roughly 20 runs in NIPA,
mostly in ipip.large, and always including some EAGAIN:
# Shouldn't coalesce if exceed IP max pkt size: Test succeeded
# Expected {65475 899 }, Total 2 packets
# Received {65475 899 }, Total 2 packets.
# Expected {64576 900 900 }, Total 3 packets
# Received {64576 /home/virtme/testing/wt-24/tools/testing/selftests/drivers/net/gro: could not receive: Resource temporarily unavailable
The test sends 2 large frames (64k + change). Looks like the default
packet socket rcvbuf (~200kB) may not be large enough to hold them.
Bump the rcvbuf to 1MB.
Add a debug print showing socket statistics to make debugging this
issue easier in the future. Without the rcvbuf increase we see:
# Shouldn't coalesce if exceed IP max pkt size: Test succeeded
# Expected {65475 899 }, Total 2 packets

We see the following failure a few times a week:
# RUN global.data_steal ...
# tls.c:3280:data_steal:Expected recv(cfd, buf2, sizeof(buf2), MSG_DONTWAIT) (10000) == -1 (-1)
# data_steal: Test failed
# FAIL global.data_steal
not ok 8 global.data_steal
The 10000 bytes read suggests that the child process did a recv()
of half of the data using the TLS ULP and we're now getting the
remaining half. The intent of the test is to get the child to
enter _TCP_ recvmsg handler, so it needs to enter the syscall before
parent installed the TLS recvmsg with setsockopt(SOL_TLS).
Instead of the 10msec sleep send 1 byte of data and wait for the
child to consume it.

The max buffer size of ENETC RX BD is 0xFFFF bytes, so if the PAGE_SIZE
is greater than 128K, ENETC_RXB_DMA_SIZE and ENETC_RXB_DMA_SIZE_XDP will
be greater than 0xFFFF, thus causing a build warning.
This will not cause any practical issues because ENETC is currently only
used on the ARM64 platform, and the max PAGE_SIZE is 64K. So this patch
is only for fixing the build warning that occurs when compiling ENETC
drivers for other platforms.

NULL pointer dereference fix.
msg_get_inq is an input field from caller to callee. Don't set it in
the callee, as the caller may not clear it on struct reuse.
This is a kernel-internal variant of msghdr only, and the only user
does reinitialize the field. So this is not critical for that reason.
But it is more robust to avoid the write, and slightly simpler code.
And it fixes a bug, see below.
Callers set msg_get_inq to request the input queue length to be
returned in msg_inq. This is equivalent to but independent from the
SO_INQ request to return that same info as a cmsg (tp->recvmsg_inq).
To reduce branching in the hot path the second also sets the msg_inq.
That is WAI.
This is a fix to commit 4d1442979e ("af_unix: don't post cmsg for
SO_INQ unless explicitly asked for"), which fixed the inverse.
Also avoid NULL pointer dereference in unix_stream_read_generic if
state->msg is NULL and msg->msg_get_inq is written. A NULL state->msg
can happen when splicing as of commit 2b514574f7 ("net: af_unix:
implement splice for stream af_unix sockets").
Also collapse two branches using a bitwise or.

When bnxt_init_one() fails during initialization (e.g.,
bnxt_init_int_mode returns -ENODEV), the error path calls
bnxt_free_hwrm_resources() which destroys the DMA pool and sets
bp->hwrm_dma_pool to NULL. Subsequently, bnxt_ptp_clear() is called,
which invokes ptp_clock_unregister().
Since commit a60fc3294a ("ptp: rework ptp_clock_unregister() to
disable events"), ptp_clock_unregister() now calls
ptp_disable_all_events(), which in turn invokes the driver's .enable()
callback (bnxt_ptp_enable()) to disable PTP events before completing the
unregistration.
bnxt_ptp_enable() attempts to send HWRM commands via bnxt_ptp_cfg_pin()
and bnxt_ptp_cfg_event(), both of which call hwrm_req_init(). This
function tries to allocate from bp->hwrm_dma_pool, causing a NULL
pointer dereference:
bnxt_en 0000:01:00.0 (unnamed net_device) (uninitialized): bnxt_init_int_mode err: ffffffed
KASAN: null-ptr-deref in range [0x0000000000000028-0x000000000000002f]

====================
net: Discard pm_runtime_put() return value
This is mostly was a resend of patches [10-12/23] from:
https://lore.kernel.org/linux-pm/6245770.lOV4Wx5bFT@rafael.j.wysocki/
as requested by Jakub, except for the last patch that has been fixed
while at it and so the version has been bumped up.
The patches are independent of each other and they are all requisite
for converting pm_runtime_put() into a void function.

The framer driver defines framer_pm_runtime_put() to return an int,
but that return value is never used. It also passes the return value
of pm_runtime_put() to the caller which is not very useful.
Returning an error code from pm_runtime_put() merely means that it has
not queued up a work item to check whether or not the device can be
suspended and there are many perfectly valid situations in which that
can happen, like after writing "on" to the devices' runtime PM "control"
attribute in sysfs for one example.
Modify phy_pm_runtime_put() to discard the pm_runtime_put() return
value and change its return type to void.
No intentional functional impact.
This will facilitate a planned change of the pm_runtime_put() return
type to void in the future.

In __sta_info_destroy_part2(), station statistics are requested after the
IEEE80211_STA_NONE -> IEEE80211_STA_NOTEXIST transition. This is
problematic because the driver may be unable to handle the request due to
the STA being in the NOTEXIST state (i.e. if the driver destroys the
underlying data when transitioning to NOTEXIST).
Move the statistics collection to before the state transition to avoid
this issue.

During the transition to use channel contexts throughout, the
ability to do injection while in monitor mode concurrent with
another interface was lost, since the (virtual) monitor won't
have a chanctx assigned in this scenario.
It's harder to fix drivers that actually transitioned to using
channel contexts themselves, such as mt76, but it's easy to do
those that are (still) just using the emulation. Do that.
