      ath9k: raise aggregation limit to 64k for HT IBSS · 313eb87f
      Sven Eckelmann authored
      mac80211 adds stations in HT IBSS as soon as a frame comes by,
      even if the HT capabilities are not known yet (they are often
      received later, e.g. in beacons). So far, ampdu factor/density
      are only calculated when the station is initially added.
      This patch changes this to update ampdu factor/density settings
      when starting a blockack session.
      Using this patch, we had performance boosts from 60 to 150 MBit/s
      between two 2x2 Atheros devices in 5 GHz HT IBSS mode.

      wlcore: print stack trace in every recovery · 680c6055
      Eyal Shapira authored
      As recovery queuing can now occur from multiple code paths
      it's convenient to know what triggered it in all cases
      other than an intended recovery which is part of the
      switch between single role to multi role.

      wlcore: queue recovery in case of bus errors during cmd_remove_peer · 6c15c1aa
      Eyal Shapira authored
      Following the addition of propagating errors from the bus ops
      there's a need to distinguish between bus errors (including timeout)
      and a legitimate timeout occuring in cmd_wait_for_event_or_timeout.
      In case of real bus errors we need to queue recovery even in cases
      where a timeout on a response from the FW to a command is acceptable.

      wlcore: fix broken TX due to wrong queuing of recovery · 7a50bdfb
      Eyal Shapira authored
      commit 14bba17b "wl12xx: Propagate errors from wl1271_raw_write32"
      breaks down TX in certain scenarios. wl1271_irq_locked() propagates
      errors from wl1271_tx_work_locked however it may return -EBUSY
      when the FW queues are full which is a legitimate case and not a
      a real error. In this case a recovery is triggered by wl1271_irq
      and this keeps repeating itself so TX is completely broken.
      Fix it by avoiding propagating return values as errors even if they
      aren't. Only bus (SDIO or SPI) ops failures would be progagated
      as only these should trigger recovery.

      wl18xx: deprecate PG1 support · e59bec16
      Luciano Coelho authored
      The new PG2 version of the chip has a few differences in terms of FW
      API if compared to PG1.  PG1 is just a sample that shouldn't be used
      in real life, so to avoid having to handle both separately, mark the
      PG1 version as deprecated and bail out during probe.

      mac80211_hwsim: fix smatch/sparse complaints · d0f718c1
      Johannes Berg authored
      The code is fine in both cases as-is, but we can
      write it slightly differently to fix smatch/sparse
       * compare the skb pointer (which we use as a cookie)
         by casting the skb to unsigned long rather than the
         cookie to a pointer (fixes "different address spaces")
       * when transmitting, data->channel must be assigned,
         don't check it (fixes "dereferenced before check")
