netxen: enable ip addr hashing

Browse Source 
NX3031 hardware requires local IP addresses for packet
accumulation (LRO). IP address hashing is required to
distinguish a local TCP flow from others (forwarded or
guest).

This patch adds listener for IP and netdev events and
configures IP address in the firmware.
