From 5628221caf88e2a052782b042e12da7cd34111b0 Mon Sep 17 00:00:00 2001 From: Daniel Drake Date: Tue, 10 Jul 2007 19:32:10 +0200 Subject: [PATCH] mac80211: ERP IE handling improvements The "protection needed" flag is currently parsed out of the ERP IE in beacons. This patch allows the ERP IE to be available at assocation time and causes the appropriate actions to be performed earlier. It is slightly complicated by the fact that most APs don't include the ERP IE in association responses. To work around this, we store ERP values in the ieee80211_sta_bss structure. Also added some WLAN_ERP defines for use by upcoming patches. Signed-off-by: Jiri Benc Signed-off-by: John W.
