From 986a8abfc51e66c96f9d39529a6ff0443fcd2591 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Wed, 5 Nov 2014 20:51:15 +0100 Subject: mac802154: move interface add handling in iface This patch moves and renames the mac802154_add_iface and mac802154_netdev_register functions into iface.c. The function mac802154_add_iface is renamed to ieee802154_if_add which is a similar naming convention like mac80211.
