    ath9k: switch to using mac80211 intermediate software queues
    
    Provides a nice latency reduction under load, due to mac80211's fq_codel
    support.

+Subject: [PATCH] ath9k: Switch to using mac80211 intermediate software queues.
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This switches ath9k over to using the mac80211 intermediate software
+queueing mechanism for data packets. It removes the queueing inside the
+driver, except for the retry queue, and instead pulls from mac80211 when
+a packet is needed. The retry queue is used to store a packet that was
+pulled but can't be sent immediately.
+
+The old code path in ath_tx_start that would queue packets has been
+removed completely, as has the qlen limit tunables (since there's no
+longer a queue in the driver to limit).
+
+Based on Tim's original patch set, but reworked quite thoroughly.
