Firmware expects 'max_ssid_length' field in
'struct mwifiex_ie_types_wildcard_ssid_params' to be '0' for
performing SSID specific scan. Currently driver updates it with
an actual SSID length. Hence UUT is not able to find the AP
configured in hidden SSID mode in scan results and association
fails.
max_ssid_length is filled with '0' to fix the issue.

The AH4/6 ahash input callbacks read out the nexthdr field from the AH
header *after* they overwrite that header. This is obviously not going
to end well. Fix it up.

The AH4/6 ahash output callbacks pass nexthdr to xfrm_output_resume
instead of the error code. This appears to be a copy+paste error from
the input case, where nexthdr is expected. This causes the driver to
continuously add AH headers to the datagram until either an allocation
fails and the packet is dropped or the ahash driver hits a synchronous
fallback and the resulting monstrosity is transmitted.
Correct this issue by simply passing the error code unadulterated.

When the connection monitor timer fires right before
suspend, the following will happen:
timer fires -> monitor_work gets queued
suspend calls ieee80211_sta_quiesce
ieee80211_sta_quiesce:
- deletes timer
- cancels monitor_work synchronously, running it
[note wrong order of these steps]
monitor_work runs, re-arming the timer
later, timer fires while system should be quiesced
This causes a warning:
WARNING: at net/mac80211/util.c:540 ieee80211_can_queue_work+0x35/0x40 [mac80211]()
but is otherwise harmless. I'm not completely sure

Commit 4d9d88d1 by Scott James Remnant <keybuk@google.com> added
the .uevent() callback for the regulatory device used during
the platform device registration. The change was done to account
for queuing up udev change requests through udevadm triggers.
The change also meant that upon regulatory core exit we will now
send a uevent() but the uevent() callback, reg_device_uevent(),
also accessed last_request. Right before commiting device suicide
we free'd last_request but never set it to NULL so
platform_device_unregister() would lead to bogus kernel paging
request. Fix this and also simply supress uevents right before
we commit suicide as they are pointless.
This fix is required for kernels >= v2.6.39
$ git describe --contains 4d9d88d1
v2.6.39-rc1~468^2~25^2^2~21
The impact of not having this present is that a bogus paging
access may occur (only read) upon cfg80211 unload time. You
may also get this BUG complaint below. Although Johannes
could not reproduce the issue this fix is theoretically correct.

The driver used NET_IP_ALIGN to remove some additional padding inside of
the rx_fixup function. On many architectures NET_IP_ALIGN defaults to 2
which removed the correct amount of bytes.
On MCORE2-machines commit ea812ca1b06113597adcd8e70c0f84a413d97544
introduces a change which sets NET_IP_ALIGN to 0 by default. Which
triggered the bug on these machines.
This fix introduces a new RXW_PADDING define and uses this instead of
NET_IP_ALIGN. The name was taken from the original SMSC7500 driver which
is provided by SMSC.

The link down would occur when reseting PHY. And it would take about 2 ~ 5 seconds
from link down to link up. If the delay of pm_schedule_suspend is not long enough,
the device would enter runtime_suspend before link up. After link up, the device
would wake up and reset PHY again. Then, you would find the driver keep in a loop
of runtime_suspend and rumtime_resume.

.. with new name. Because nothing says "really solid kernel release"
like naming it after an extinct animal that just happened to be in the
news lately.
Mountpoint crossing is similar to following procfs symlinks - we do
not get ->d_revalidate() called for dentry we have arrived at, with
unpleasant consequences for NFS4.
Simple way to reproduce the problem in mainline:
cat >/tmp/a.c <<'EOF'
#include <unistd.h>
#include <fcntl.h>
#include <stdio.h>
main()
{
struct flock fl = {.l_type = F_RDLCK, .l_whence = SEEK_SET, .l_len = 1};
if (fcntl(0, F_SETLK, &fl))
perror("setlk");
}
EOF
cc /tmp/a.c -o /tmp/test
then on nfs4:
mount --bind file1 file2
/tmp/test < file1 # ok
/tmp/test < file2 # spews "setlk: No locks available"...
What happens is the missing call of ->d_revalidate() after mountpoint
crossing and that's where NFS4 would issue OPEN request to server.
The fix is simple - treat mountpoint crossing the same way we deal with
following procfs-style symlinks. I.e. set LOOKUP_JUMPED...

Rx byte count was off; instead use the hardware's count. Tx packet
count was counting pre-TSO packets; instead count on-the-wire packets.
Report hardware dropped frame count as rx_fifo_errors.
- The count of transmitted packets reported by the forcedeth driver
reports pre-TSO (TCP Segmentation Offload) packet counts and not the
count of the number of packets sent on the wire. This change fixes
the forcedeth driver to report the correct count. Fixed the code by
copying the count stored in the NIC H/W to the value reported by the
driver.
- Count rx_drop_frame errors as rx_fifo_errors:
We see a lot of rx_drop_frame errors if we disable the rx bottom-halves
for too long. Normally, rx_fifo_errors would be counted in this case.
The rx_drop_frame error count is private to forcedeth and is not
reported by ifconfig or sysfs. The rx_fifo_errors count is currently
unused in the forcedeth driver. It is reported by ifconfig as overruns.
This change reports rx_drop_frame errors as rx_fifo_errors.
