From e8975581f63870be42ff4662b293d1b0c8c21350 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 9 Oct 2008 12:18:51 +0200 Subject: mac80211: introduce hw config change flags This makes mac80211 notify the driver which configuration actually changed, e.g. channel etc. No driver changes, this is just plumbing, driver authors are expected to act on this if they want to. Also remove the HW CONFIG debug printk, it's incorrect, often we configure something else. Signed-off-by: Johannes Berg Signed-off-by: John W.
