From f23a478075659db8a4fd62fa6e264a8bb052cc5b Mon Sep 17 00:00:00 2001 From: Arik Nemtsov Date: Mon, 8 Nov 2010 11:51:06 +0200 Subject: mac80211: support hardware TX fragmentation offload The lower driver is notified when the fragmentation threshold changes and upon a reconfig of the interface. If the driver supports hardware TX fragmentation, don't fragment packets in the stack. Signed-off-by: Arik Nemtsov Signed-off-by: John W.
