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

From: Jérôme Pouiller <jerome.pouiller@...abs.com>

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


Jérôme Pouiller (32):
  staging: wfx: add sanity checks to hif_join()
  staging: wfx: do not stop mac80211 queueing during tx_policy upload
  staging: wfx: take advantage of ieee80211_{stop/start}_queues

  staging: wfx: simplify wfx_tx_queue_mask_get()
  staging: wfx: drop useless sta_asleep_mask
  staging: wfx: drop argument tx_allowed_mask since it is constant now
  staging: wfx: do not use link_map_cache to track CAB
  staging: wfx: drop useless link_map_cache
  staging: wfx: do not rely anymore on link_id to choose packet in queue
  staging: wfx: drop unused link_id field
  staging: wfx: drop unused raw_link_id field

  staging: wfx: relocate wfx_skb_dtor() prior its callers
  staging: wfx: repair wfx_flush()
  staging: wfx: wfx_flush() did not ensure that frames are processed
  staging: wfx: fix potential deadlock in wfx_tx_flush()
  staging: wfx: fix case where AP stop with CAB traffic pending
  staging: wfx: remove hack about tx_rate policies
