From 06cc5d3bb01350466f7a1bf64d9afe06870b6480 Mon Sep 17 00:00:00 2001 From: Vidhya Govindan Date: Tue, 17 Nov 2009 18:49:54 +0200 Subject: [PATCH] wl1251: Send null data packet with "TODS" bit set According to IEEE80211 standard all the data packets have to be sent with TODS bit set. This patch fixes the null data packet format which was sent without TODS bit set. This should fix many problems associated with power save. Janne Ylalehto also found this fix in the same time as mine, for a different bug he was working on.
