From d057e5a381cbaec5632117bf62ba49438ab16214 Mon Sep 17 00:00:00 2001 From: Arik Nemtsov Date: Mon, 31 Jan 2011 22:29:13 +0200 Subject: mac80211: add HW flag for disabling auto link-PS in AP mode When operating in AP mode the wl1271 hardware filters out null-data packets as well as management packets. This makes it impossible for mac80211 to monitor the PS mode by using the PM bit of incoming frames. Implement a HW flag to indicate that mac80211 should ignore the PM bit. In addition, expose ieee80211_sta_ps_transition() to make low-level drivers capable of controlling PS-mode. Signed-off-by: Arik Nemtsov Signed-off-by: John W.
