From 17c18bf880b2464851e5a2bca86521affc46c97e Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Sat, 21 Mar 2015 15:25:43 +0100 Subject: mac80211: add TX fastpath In order to speed up mac80211's TX path, add the "fast-xmit" cache that will cache the data frame 802.11 header and other data to be able to build the frame more quickly. This cache is rebuilt when external triggers imply changes, but a lot of the checks done per packet today are simplified away to the check for the cache. There's also a more detailed description in the code.
