Subject: [PATCH] mac80211: Checking for zero Len subframe's only when driver supports the reporting of zero len subframes.
Date: Fri, 07 Dec 2012 16:11:57 +0530	[thread overview]
Message-ID: <50C1C7F5.6010808@posedge.com> (raw)
In-Reply-To: <201212071036.qB7Aas8o001865@chaitanya-desktop>



Zero Len subframe makes sense only when driver supports the reporting
of zero len subframes.(to handle buggy drivers)
