From f434b2d111d9ff84ebdd0f11a7ae42c761453259 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 10 Jul 2008 11:22:31 +0200 Subject: [PATCH] mac80211: fix struct ieee80211_tx_queue_params Multiple issues: - there are no "default" values needed - cw_min/cw_max can be larger than documented - restructure to decrease size - use get_unaligned_le16 Signed-off-by: Johannes Berg Signed-off-by: John W.
