Description
The NDP and ARP entries in the ASIC are indexed by IP address only. If Illumos believes that the same address is available via different ports, it will attempt to insert conflicting entries with undefined behavior. We should eliminate this ambiguity by including the port number as part of the table key.

Research direction
Start by locating the ASIC ARP and NDP table definitions and the code that constructs their keys. Trace how entries from Illumos are inserted, especially when the same IP address appears on multiple ports. Done means the port number participates in both table keys and same-address entries on different ports no longer conflict.
