Add support for IPv6 nexthop/blackhole/connected routes for Marvell
Prestera driver.
Handle AF_INET6 neigbours, fib entries.

Add features:
 - IPv6:
   - Support "offload", "offload_failed", "trap" flags
   - Support blackhole, nexthop, local/connected/unreachable/etc (trap)
     e.g.: "ip addr add 2001:1::1/64 dev sw1p2"
     e.g.: "ip route add 2002:2::/64 via 2001:2::2"
     e.g.: "ip route add blachole 2003:2::/64 dev lo"

 - ipv6 ECMP is not supported
 - Only "local" and "main" tables supported
 - Only generic interfaces supported for router (no bridges or vlans)
