From 725b812c839643639d6135b1f7fb41e48de465a4 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 10 Apr 2015 14:02:08 +0200 Subject: [PATCH] mac80211: extend fast-xmit to driver fragmentation If the driver handles fragmentation then it wouldn't be done in software so we can still use the fast-xmit path in that case.
