[hme interface]

Yes, one in particular is Cisco switches will not see an autonegotiate
preamble on the wire and will default to 100-half if they are set to
autonegotiate.

I don't know the full story, but disabling auto-negotiation for
a Sunswift add-on interface was our solution for negotiation problems.

This is an ancient hme device (100 Mb/s, and SCSI) added to an
Ultra-1. Other Suns on the same wire have no problems with
autonegotiation. For the sunswift card, setting both ends 100Mb/s
full worked. The troublesome behavior was repeatable with multiple
switches.
