From 9ed6bcce77f75d98af6ee07069deac6041948bee Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 8 May 2009 20:47:39 +0200 Subject: [PATCH] mac80211: move HT operation mode BSS info There really is no need to have a separate struct for a single variable. The fact that it exists is due to the code legacy, but we can remove that now. Very simple. Signed-off-by: Johannes Berg Signed-off-by: John W.
