[Patch v2 4/5] mwifiex: do not setup AMPDU/AMSDU with broadcast receiver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Avinash Patil <patila@xxxxxxxxxxx>

It is observed that device sometimes sends BA setup requests for
broadcast mac address.
This patch adds a check to avoid checking availability of
AMPDU/AMSDU streams for broadcast mac address.
