mac802154: rename mac802154_priv to ieee802154_local
This patch rename the mac802154_priv to ieee802154_local. The mac802154_priv structure is like ieee80211_local and so we name it ieee802154_local. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
