[PATCH 14/32] staging: wfx: do not use link_map_cache to track CAB

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

 



From: Jérôme Pouiller <jerome.pouiller@xxxxxxxxxx>

Since we do not track power save status of the stations anymore,
link_map_cache is now only used to track "Content After (DTIM) Beacon".
We prefer to rely on flags from tx_info. So we will be able to drop
link_map_cache.
