From 98f0b0a3a412eade153c7cf00c6b863600980d89 Mon Sep 17 00:00:00 2001 From: Ron Rindjunsky Date: Tue, 18 Dec 2007 17:23:53 +0200 Subject: mac80211: pass in PS_POLL frames This patch fixes should_drop_frame function to pass in ps poll control frames required for power save functioanlity. Interface types that do not have interest for PS POLL frames now drop it in handler. Signed-off-by: Ron Rindjunsky Acked-by: Johannes Berg Signed-off-by: John W. Linville Signed-off-by: David S.
