[PATCH 00/32] staging: wfx: rework the Tx queue

From: Jerome Pouiller

From: JÃrÃme Pouiller <jerome.pouiller@xxxxxxxxxx>

This current implementation of the Tx queue is far more complex than
necessary and its behavior is dubious on some corner cases. This series
rework the Tx queue:
- Simplify support for QoS (since device already do the job)
- Simplify support for Power Saving stations (since mac80211 already
do the job)
- Improve support of Content After DTIM Beacon (CAB) when device is
AP and some station use power save.
- Improve robustness of flushing


JÃrÃme Pouiller (32):
staging: wfx: add sanity checks to hif_join()
