From 31eba5bc56a9324f056d28569a4f89f39c1c3f70 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Tue, 28 May 2013 13:01:53 +0200 Subject: mac80211: support active monitor interfaces Support them only if the driver advertises support for them via IEEE80211_HW_SUPPORTS_ACTIVE_MONITOR. Unlike normal monitor interfaces, they are added to the driver, along with their MAC address.
