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. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
