Hello,

This one break monitor mode for qca988x and 10.x firmware:
After Revert "ath10k: remove supported chain mask" - works correctly.

Janusz,

Thanks for reporting. Will send out patch asap.

Janusz,

It seems the change ("ath10k: remove supported chain mask") just exposed an
hidden problem. The same target assert can be reproduced by below sequence
even after reverting the commit.

ifconfig wlan0 down
iw wlan0 set type monitor
iw phy0 set antenna 7
ifconfig wlan0 up

The actual cause of target assert is below commit.

    ath10k: apply chainmask settings to vdev on creation

Configuring NSS vdev param on interface addition is causing the target assert in 10.1 firmware.
Just creating monitor interface is causing assert with qca_main firmware.
