Subject: [PATCH] ath9k: add back support for using active monitor interfaces
|
||
|
|
for tx99
|
||
|
|
|
||
|
|
Various documented examples on how to set up tx99 with ath9k rely
|
||
|
|
on setting up a regular monitor interface for setting the channel.
|
||
|
|
My previous patch "ath9k: fix tx99 with monitor mode interface" made
|
||
|
|
it possible to set it up this way again. However, it was removing support
|
||
|
|
for using an active monitor interface, which is required for controlling
|
||
|
|
the bitrate as well, since the bitrate is not passed down with a regular
|
||
|
|
monitor interface.
|
||
|
|
|
||
|
|
This patch partially reverts the previous one, but keeps support for using
|
||
|
|
a regular monitor interface to keep documented steps working in cases
|
||
|
|
where the bitrate does not matter
|
||
|
|
|
||
|
|
Fixes: d9c52fd17cb48 ("ath9k: fix tx99 with monitor mode interface")
