Subject: [PATCH] mac80211: fix remain_off_channel regression
|
|
|
44ef27d |
|
|
|
44ef27d |
The offchannel code is currently broken - we should
|
|
|
44ef27d |
remain_off_channel if the work was started, and
|
|
|
44ef27d |
the work's channel and channel_type are the same
|
|
|
44ef27d |
as local->tmp_channel and local->tmp_channel_type.
|
|
|
44ef27d |
|
|
|
44ef27d |
However, if wk->chan_type and local->tmp_channel_type
|
|
|
44ef27d |
coexist (e.g. have the same channel type), we won't
|
|
|
44ef27d |
remain_off_channel.
|
|
|
44ef27d |
|
|
|
44ef27d |
This behavior was introduced by commit da2fd1f
|
|
|
44ef27d |
("mac80211: Allow work items to use existing
|
|
|
44ef27d |
channel type.")
