[PATCH net-next v5 06/13] mac802154: slave interfaces declaration

[Alexander Smirnov <alex.bluesman.smirnov@gmail.com>]

Slaves represent typical network interfaces available from userspace.
Each ieee802154 device/transceiver may have several slaves and able
to be associated with several networks at the same time. So this
patch adds structure for slaves declaration.
