Networking IPv6:  Fix and error when adding a neighbor to the table.  Comparing wrong address.  Add more debug info too

Networking:  IPv6 receipt logic errors.  Don't save neighbor address in table when solicitation is recieved.  Save it when the advertisement is received

All Ethernet drivers (again):  Missed one place where arp_out() is called and neighber_out() needs to be called

ICMPv6 Neighbor Advertisement:  Need to set O flag or response is not used.  Also, TTL=255 seems to be more-or-less standard in this message

Correct name of fields in struct sockaddr_in6:  sin6_port and sin6_family, not sin_port and sin_family

Networking:  When sending ICMPv6 advertisements and solicitations, set the NOARP bit so that we don't overwrite the destination MAC address

Networking:  Modify all Ethernet drivers:  Do neighbor look-up on all outgoing IPv6 packs in order to properly set the destination link layer address.

Networking:  Add logic to search the Neighbor Table and update the destination address in the output Ethernet header OR to send an ICMPv6 Neighbor Solicitation if there is no entry in the Neighbor table for the IPv6 address

Networking:  Fix to ICMPv6 logic: Needs to set source and destination address in the Ethernet header
