When the queue is unmapped while it was so loaded that
|
|
mac80211's was stopped, we need to wake the queue after
|
|
having freed all the packets in the queue.
|
|
Not doing so can result in weird stuff like:
|
|
|
|
* run lots of traffic (mac80211's queue gets stopped)
|
|
* RFKILL
|
|
* de-assert RFKILL
|
|
* no traffic
|
