From 7c118c1a866454cf2091fd84404d0915a27b0eef Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Wed, 5 Nov 2014 20:51:20 +0100 Subject: mac802154: add ieee802154_vif struct This patch adds an ieee802154_vif similar like the ieee80211_vif which holds the interface type and maybe further more attributes like the ieee80211_vif structure.
