Subject: [PATCH] brcmfmac: reduce timeout for action frame scan
|
|
|
|
Finding a common channel to send an action frame out is required for
|
|
some action types. Since a loop with several scan retry is used to find
|
|
the channel, a short wait time could be considered for each attempt.
|
|
This patch reduces the wait time from 1500 to 450 msec for each action
|
|
frame scan.
|
|
|
|
This patch fixes the WFA p2p certification 5.1.20 failure caused by the
|
|
long action frame send time.
