From 3e2a0226c624066943259eaa5e1261da9d8a25fc Mon Sep 17 00:00:00 2001 From: Luciano Coelho Date: Sat, 5 Jul 2014 11:43:01 +0300 Subject: [PATCH] mac80211: remove redundant IEEE80211_STA_CSA_RECEIVED flag The csa_active flag was added in sdata a while ago and made IEEE80211_STA_CSA_RECEIVED redundant. The new flag is also used to mark when CSA is ongoing on other iftypes and took over the old one as the preferred method for checking whether we're in the middle of a channel switch. Remove the old, redundant flag.
