There is another reason I want the cache flushed.
Those hh cache entries are what ARP resolved to when we
had the previous MAC address, not the one we have now.
The ARPs may come back differently with the new MAC
address.
I _REALLY REALLY_ don't want to have to change the
->update() implementations. Although one thing I
would consider is a new ->update_src() operation
and if this were NULL we flush the entries instead.
