From adf5ace5d8161b962afe90e77922728a425b6933 Mon Sep 17 00:00:00 2001 From: Helmut Schaa Date: Thu, 8 Dec 2011 13:11:55 +0100 Subject: [PATCH] mac80211: Make use of ieee80211_is_* functions in tx status path Use ieee80211_is_data, ieee80211_is_mgmt and ieee80211_is_first_frag in the tx status path. This makes the code easier to read and allows us to remove two local variables: frag and type. Signed-off-by: Helmut Schaa Signed-off-by: John W.
