From d50529c0d8b7f03012f140349161c29b0f7bd24c Mon Sep 17 00:00:00 2001 From: Eliad Peller Date: Thu, 22 Nov 2012 18:06:20 +0200 Subject: [PATCH] wlcore: pass wmm configuration to the fw New fields were added to start_role(ap) and set_peer_state commands, so the fw will be able to know whether the sta/ap supports wmm (the fw uses it in order to choose the AC for some of its internally-generated frames) For sta, take this value right from bss_conf->qos. For ap, check for wmm support by looking for the WMM IE in the configured beacon.
