one from before I re-negotiated the link:
hme0: error signaled, status=0x3000400
from that time there are collisions on the interface but no new
and no if{In,Out}Errors but
bz@pizza:~> netstat -I hme0

I had been able to test things with an additional xl0
in the sparc last hour;
same results: 7-8MBit/s RX but only 3-4Mbit/s TX.
