From f546638c3f809fdacddc03fe765669c3042e0d9d Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 9 Dec 2008 12:30:03 +0100 Subject: mac80211: remove fragmentation offload functionality There's no driver that actually does fragmentation on the device, and the callback is buggy (when it returns an error, mac80211's fragmentation status is changed so reading the frag threshold from userspace reads the new value despite the error). Let's just remove it, if we really find some hardware supporting it we can add it back later. Signed-off-by: Johannes Berg Signed-off-by: John W.
