From e3b90ca28412fb9dcc8c5ca38e179e78fec07eee Mon Sep 17 00:00:00 2001 From: Igor Perminov Date: Tue, 4 Aug 2009 16:48:51 +0400 Subject: mac80211: FIF_PSPOLL filter flag When an interface is configured in the AP mode, the mac80211 implementation doesn't inform the driver to receive PS Poll frames. It leads to inability to communicate with power-saving stations reliably. The FIF_CONTROL flag isn't passed by mac80211 to ieee80211_ops.configure_filter when an interface is in the AP mode. And it's ok, because we don't want to receive ACK frames and other control ones, but only PS Poll ones. This patch introduces the FIF_PSPOLL filter flag in addition to FIF_CONTROL, which means for the driver "pass PS Poll frames". This flag is passed to the driver: A) When an interface is configured in the AP mode. B) In all cases, when the FIF_CONTROL flag was passed earlier (in addition to it).
