From 8fe02e167efa8ed4a4503a5eedc0f49fcb7e3eb9 Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Mon, 21 Oct 2013 19:22:25 +0200 Subject: cfg80211: consolidate passive-scan and no-ibss flags These two flags are used for the same purpose, just combine them into a no-ir flag to annotate no initiating radiation is allowed. Old userspace sending either flag will have it treated as the no-ir flag. To be considerate to older userspace we also send both the no-ir flag and the old no-ibss flags. Newer userspace will have to be aware of older kernels. Update all places in the tree using these flags with the following semantic patch: @@ @@ -NL80211_RRF_PASSIVE_SCAN +NL80211_RRF_NO_IR @@ @@ -NL80211_RRF_NO_IBSS +NL80211_RRF_NO_IR @@ @@ -IEEE80211_CHAN_PASSIVE_SCAN +IEEE80211_CHAN_NO_IR @@ @@ -IEEE80211_CHAN_NO_IBSS +IEEE80211_CHAN_NO_IR @@ @@ -NL80211_RRF_NO_IR | NL80211_RRF_NO_IR +NL80211_RRF_NO_IR @@ @@ -IEEE80211_CHAN_NO_IR | IEEE80211_CHAN_NO_IR +IEEE80211_CHAN_NO_IR @@ @@ -(NL80211_RRF_NO_IR) +NL80211_RRF_NO_IR @@ @@ -(IEEE80211_CHAN_NO_IR) +IEEE80211_CHAN_NO_IR Along with some hand-optimisations in documentation, to remove duplicates and to fix some indentation.

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).
