      ath9k: Add wiphy name to log messages. · 98b36a02
      Ben Greear authored
      On systems with multiple NICs, it's nice to know which
      one is producing warnings.  Here is an example of the
      new ouput:
      ath: wiphy0: Failed to stop TX DMA, queues=0x005!

      mac80211: Limit TID buffering during BA session setup/teardown · aa454580
      Helmut Schaa authored
      While setting up or tearing down a BA session mac80211 is buffering
      pending frames for the according TID. However, there's currently no
      limit on how many frames are buffered possibly leading to an out-of-
      memory situation. This can happen on systems with little memory when
      the CPU is fully loaded since the BA session work is executed in
      process context while frames can still come via softirq.
      Apply a limitation to the TIDs pending queue to avoid consuming
      too much memory in this situation.

      ath9k: Fix BTCOEX shutdown · bff2ec2b
      Sujith Manoharan authored
      Flush MCI profiles only if MCI is being actually used.
      This fixes a panic on driver unload when non-MCI devices
      are being used and btcoex_enable is set.
