Subject: [PATCH] ath9k: Fix offchannel flush timeout
|
|
|
|
An offchannel operation also needs to have
|
|
a flush timeout that doesn't exceed the NoA
|
|
absence duration of a GO context, so use
|
|
channel_switch_time. The first offchannel
|
|
operation is set a flush timeout of 10ms since
|
|
channel_switch_time will be zero.
|
