From d18da7fcca449f09c91a209b4f5006959c5a7656 Mon Sep 17 00:00:00 2001 From: Eyal Shapira Date: Tue, 31 Jan 2012 11:57:25 +0200 Subject: [PATCH] wl12xx: change WLVIF_FLAG_PSM name and remove WLVIF_FLAG_PSM_REQUESTED WLVIF_FLAG_PSM turned to WLVIF_FLAG_IN_AUTO_PS which marks that this vif is in AUTO PS. WLVIF_FLAG_PSM_REQUESTED is not required as mac80211 calls op_config with CONF_PS after association. wl12xx_config_vif() handling of CONF_PS was simplified and cleaned up.
