From e327b847e67051ece8d121f9aebeb4d736c36a02 Mon Sep 17 00:00:00 2001 From: "John W. Linville" Date: Mon, 1 Dec 2008 14:56:41 -0500 Subject: [PATCH] mac80211: deauth when interface is marked down It seems like proper etiquette to let other stations know when we are going down in either STA or IBSS mode. This also notifies userland, so wpa_supplicant doesn't get confused. Signed-off-by: John W.
