From fa9ffc745610f31c6bc136d5a6a1782e00870e72 Mon Sep 17 00:00:00 2001 From: Kyeyoon Park Date: Mon, 16 Dec 2013 23:01:30 -0800 Subject: cfg80211: Add support for QoS mapping This allows QoS mapping from external networks to be implemented as defined in IEEE Std 802.11-2012, 10.24.9. APs can use this to advertise DSCP ranges and exceptions for mapping frames to a specific UP over Wi-Fi. The payload of the QoS Map Set element (IEEE Std 802.11-2012, 8.4.2.97) is sent to the driver through the new NL80211_ATTR_QOS_MAP attribute to configure the local behavior either on the AP (based on local configuration) or on a station (based on information received from the AP).
