Subject: [PATCH] ath9k: fix tx99 with monitor mode interface
|
|
|
|
Tx99 is typically configured via a monitor mode interface, which does
|
|
not get added to the driver as a vif. Since the code currently expects
|
|
a configured virtual interface for tx99, enabling tx99 via debugfs fails.
|
|
Since the vif is not needed anyway, remove all checks for it.
