Subject: [PATCH] mac80211: disable power save if an infra AP vif exists
Date: Tue, 1 Feb 2011 00:15:18 +0530	[thread overview]
Message-ID: <1296499518-3895-1-git-send-email-rmanoharan@atheros.com> (raw)

PS should not be enabled if an infra AP vif exists in
the interface list. So while recalculating PS,
AP vif type should be taken into account.
