From d75bb06b61cb69ee6223d791d3bb230e68623b20 Mon Sep 17 00:00:00 2001 From: Gautam Kumar Shukla Date: Tue, 23 Dec 2014 16:55:19 +0100 Subject: cfg80211: add extensible feature flag attribute With the wiphy::features flag being used up this patch adds a new field wiphy::ext_features. Considering extensibility this new field is declared as a byte array. This extensible flag is exposed to user-space by NL80211_ATTR_EXT_FEATURES.
