Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: fix WARN_ON for monitor mode on some devices
On devices without WANT_MONITOR_VIF (and probably without
channel context support) we get a WARN_ON for changing the
per-link setting of a monitor interface.
Since we already skip AP_VLAN interfaces and MONITOR with
WANT_MONITOR_VIF and/or NO_VIRTUAL_MONITOR should update
the settings, catch this in the link change code instead
of the warning.
