I'm not sure. It would add an ether_cmp() to a criticial path, but unlike
the smc91cxx.c case not only in promiscuous mode. Maybe it should only check
that if we are in half-duplex mode?

But on the other hand, the current solution does not cause any performance
hit and works - what's the problem with it?


P.S.: btw: while searching for docs on the hme I ran accross notions of it
being able to do hardware checksums, is there any reason we do not use that
