From 1c7e23bf50264a251de53ad9fb1604683b801258 Mon Sep 17 00:00:00 2001 From: Assaf Krauss Date: Wed, 3 Sep 2014 15:25:00 +0300 Subject: [PATCH] nl80211: Allow declaring RRM-related features Radio Resource Measurement (RRM) is a bundle of features which will require the entire stack to participate. In this patch, the driver is given the opportunity to advertise the device's support for these RRM-related features, using feature flags: 1. Support for Quiet IEs. 2. Support for adding DS Parameter Set IE to probe requests. 3. Support for adding WFA TPC Report IE to probe requests. 4. Support for inserting tx power value to tx-ed packets at a fixed offset. This is used in action frames, such as RRM's Link Measurement Report, where the actual tx power should be reported in the frame.
