From bab5ab7d2a5466406e8003d038cc7ce6b2d5d804 Mon Sep 17 00:00:00 2001 From: Assaf Krauss Date: Wed, 3 Sep 2014 15:25:01 +0300 Subject: nl80211: Add flag attribute for RRM connections Add a flag attribute to use in associations, for tagging the target connection as supporting RRM. It is the responsibility of upper layers to set this flag only if both the underlying device, and the target network indeed support RRM. To be used in ASSOCIATE and CONNECT commands.
