nl80211: Allow declaring RRM-related features (1c7e23bf) · Commits · 戴 / test

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. Signed-off-by:
