From 59d19cd70cd38afd2d9bf2e3b48c3a5bbb630b5a Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Sat, 25 Oct 2014 17:16:40 +0200 Subject: mac802154: introduce IEEE802154_DEV_TO_SUB_IF This function adds a wrapper to call netdev_priv to getting the sdata attribute. This is similar like the IEEE80211_DEV_TO_SUB_IF function inside wireless stack implementation.
