From cb831b537d50d21f6afb5dffbde4cf6523627461 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 2 Jul 2012 15:40:18 +0200 Subject: mac80211: remove tx_frags driver callback The implementation of tx_frags is buggy due to not handling queue stop, and there's no driver implementing it so remove it.
