Add initial router support for Marvell Prestera driver.
Subscribe on inetaddr notifications. TRAP packets, that has to be routed
(if packet has router's destination MAC address).

Add features:
 - Support ip address adding on port.
   e.g.: "ip address add PORT 1.1.1.1/24"

Limitations:
 - Only regular port supported. Vlan will be added soon.
 - It is routing through CPU. Offloading will be added in
   next patches.
