This patch series includes some fixes when the device
is in recovery mode, i.e. when the firmware goes down.

- Pausing TX queues when FW goes down
- Removed unwanted/extra error logging in pkt TX path
- Skipping wait for FW response for delete cmds
- Handling the -ESHUTDOWN error code in case of SSR.

When the FW goes down, the transmission of
packets cannot be done. Currently we are not
pausing the tx queues, hence there will be too
many attempts to trasmit packets and each of
them resulting in failure and thereby logging
unwanted failure messages onto the console,
as shown below

[   60.842192] ath10k_snoc 18800000.wifi: failed to transmit packet, dropping: -108
[   60.850181] ath10k_snoc 18800000.wifi: failed to submit frame: -108
[   60.857058] ath10k_snoc 18800000.wifi: failed to push frame: -108
[   60.936217] ath10k_snoc 18800000.wifi: failed to transmit packet, dropping: -108
[   60.944496] ath10k_snoc 18800000.wifi: failed to submit frame: -108
[   60.951265] ath10k_snoc 18800000.wifi: failed to push frame: -108
[   61.976589] ath10k_snoc 18800000.wifi: failed to transmit packet, dropping: -108

Stop the tx queues when the wlan firmware is
down and also remove the unwanted duplicate/extra
logging in the packet transmission path.

Currently the driver waits for response from the
firmware for all the delete cmds, eg: vdev_delete,
peer delete. If the firmware is down, these wait
will always timeout and return an error.

Also during subsytems recovery, any attempt to
send a WMI cmd to the FW will return the -ESHUTDOWN
status, which when returned to mac80211, can cause
unnecessary warnings to be printed on to the console,
as shown below

[ 2559.529565] Call trace:

Skip the wait for delete response from the
firmware if the firmware is down. Also return
success to the mac80211 calls when the peer delete
cmd fails with return status -ESHUTDOWN.

Don't you mean !test_bit(ATH10K_FLAG_CRASH_FLUSH, &ar->dev_flags))  ???

Or maybe I'm just mis-reading your patch?
