mac802154: rename mac802154_sub_if_data
Like wireless this structure should named ieee802154_sub_if_data and not mac802154_sub_if_data. This patch renames the struct and variables to sdata instead priv sometimes. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
