NETLINK_MAX_FMTMSG_LEN is currently hardcoded to 80, and we provide an
error printf-formatted string having 96 characters including the
terminating \0. Assuming each %d (representing a queue) gets replaced by
a number having at most 2 digits (a reasonable assumption), the final
string is also 96 characters wide, which is too much.
Reduce the verbiage a bit by removing some (partially) redundant words,
which makes the new printf-formatted string be 73 characters wide with
the trailing newline.

AcceptMulticast if IFF_MULTICAST isn't set.
Note: Based on the implementations I've seen it doesn't seem to be 100% clear
what a driver is supposed to do if IFF_ALLMULTI is set but IFF_MULTICAST
is not. This patch is based on the understanding that IFF_MULTICAST has

The TX ring maintained by the tg3 driver can end up in the state, when it
has packets queued for sending but the NIC hardware is not informed, so no
progress is made. This leads to a multi-second interruption in network
traffic followed by dev_watchdog() firing and resetting the queue.
The specific sequence of steps is:
1. tg3_start_xmit() is called at least once and queues packet(s) without
updating tnapi->prodmbox (netdev_xmit_more() returns true)
2. tg3_start_xmit() is called with an SKB which causes tg3_tso_bug() to be
called.
3. tg3_tso_bug() determines that the SKB is too large, ...
if (unlikely(tg3_tx_avail(tnapi) <= frag_cnt_est)) {
... stops the queue, and returns NETDEV_TX_BUSY:
netif_tx_stop_queue(txq);
...
if (tg3_tx_avail(tnapi) <= frag_cnt_est)
return NETDEV_TX_BUSY;
4. Since all tg3_tso_bug() call sites directly return, the code updating
tnapi->prodmbox is skipped.
5. The queue is stuck now. tg3_start_xmit() is not called while the queue
is stopped. The NIC is not processing new packets because
tnapi->prodmbox wasn't updated. tg3_tx() is not called by
tg3_poll_work() because the all TX descriptions that could be freed has
been freed:
/* run TX completion thread */
if (tnapi->hw_status->idx[0].tx_consumer != tnapi->tx_cons) {
tg3_tx(tnapi);
6. Eventually, dev_watchdog() fires triggering a reset of the queue.
This fix makes sure that the tnapi->prodmbox update happens regardless of
the reason tg3_start_xmit() returned.

Dell R650xs servers hangs on reboot if tg3 driver calls
tg3_power_down.
This happens only if network adapters (BCM5720 for R650xs) were
initialized using SNP (e.g. by booting ipxe.efi).
The actual problem is on Dell side, but this fix allows servers

When adding a drop rule on a VF, rule direction is not being set, which
results in it always being set to ingress (ICE_ESWITCH_FLTR_INGRESS
equals 0). Because of this, drop rules added on port representors don't
match any packets.
To fix it, set rule direction in drop action to egress when netdev is a
port representor, otherwise set it to ingress.

Pull sh updates from John Paul Adrian Glaubitz:
"While the previously announced patch series for converting arch/sh to
device trees is not yet ready for inclusion to mainline and therefore
didn't make it for this pull request, there are still a small number
changes for v6.7 which include one platform (board plus CPU and driver
code) removal plus two fixes.
The removal sent in by Arnd Bergmann concerns the microdev board which
was an early SuperH prototype board that was never used in production.
With the board removed, we were able to drop the now unused code for
the SH4-202 CPU and well as the driver code for the superhyway bus and
a custom implementation for ioport_map() and ioport_unmap() which will
allow us to simplify ioport handling in the future.
Another patch set by Geert Uytterhoeven revives SuperH BIOS
earlyprintk support which got accidentally disabled in
e76fe57447 ("sh: Remove old early serial console code V2"), the
second patch in the series updates the documentation.
Finally, a patch by Masami Hiramatsu fixes a regression reported by
the kernel test robot which uncovered that arch/sh is not implementing
arch_cmpxchg_local() and therefore needs use __generic_cmpxchg_local()
instead"

The iavf client interface was added in 2017 by commit ed0e894de7
("i40evf: add client interface"), but there have never been any in-tree
callers.
It's not useful for future development either. The Intel out-of-tree
iavf and irdma drivers instead use an auxiliary bus, which is a better
solution.

Every time I create VFs on ice, I receive at least one "Device is still
in reset (-16), retrying" message per VF. It recovers fine, but typical
usecases should not trigger scary-looking messages.
The waiting for reset is too short. It makes no sense to check every 10
microseconds. Typical reset waiting times are at least tens of
milliseconds and can be several seconds. I suspect the polling interval
was meant to be 10 milliseconds all along.
IAVF_RESET_WAIT_COMPLETE_COUNT is defined as 2000, so the total waiting
time could be over 20 seconds. I have seen resets take 5 seconds (with
128 VFs on ice).
The added benefit of not triggering the "Device is still in reset" path
is that we avoid going through the __IAVF_INIT_FAILED state, which would
take a full second before retrying.

This pattern appears in two places in the iavf source code:
while (!mutex_trylock(...))
usleep_range(...);
That's just mutex_lock with extra steps.
The pattern is a leftover from when iavf used bit flags instead of
mutexes for locking. Commit 5ac49f3c27 ("iavf: use mutexes for locking
of critical sections") replaced test_and_set_bit with !mutex_trylock,
preserving the pattern.
Simplify it to mutex_lock.

In iavf_down, we're skipping the scheduling of certain operations if
the driver is being removed. However, the IAVF_FLAG_AQ_DISABLE_QUEUES
request must not be skipped in this case, because iavf_close waits
for the transition to the __IAVF_DOWN state, which happens in
iavf_virtchnl_completion after the queues are released.
Without this fix, "rmmod iavf" takes half a second per interface that's
up and prints the "Device resources not yet released" warning.

This board was an early prototype platform for early SH4 CPUs and related
to the already removed SH5 cayman platform.
The microdev board itself has been kept in the tree for this long despite
being in a bad shape even 20 years ago when it got merged, with no working
PCI support and ugly workarounds for its I/O port implementation that
try to emulate PC style peripheral access despite being quite different
in reality.
As far as I can tell, the ethernet, display, USB and PCI devices on it
already broke at some point (afbb9d8d52, 46bc858720), so I think
we can just removeit entirely.
