Subject: [PATCH] mac80211: minstrel_ht: add a small optimization to
|
||||
minstrel_aggr_check
|
||||
|
||||
Check the queue mapping earlier, skb->queue_mapping is more likely than
|
||||
skb->data to still be in d-cache.

Subject: [PATCH] mac80211: add tx_status_noskb to rate_control_ops

This op works like .tx_status, except it does not need access to the
