Hello everyone (especially David),
I'm doing a backup of my laptop with rdump on my small Ethernet network
(just the primary machine -- keltia -- and the laptop -- a Sparcbook
named sidhe) and I'm getting an awfully high number of collisions shown
by netstat.
What is weird is that the tranceiver on the sparcbook doesn't show any
collision... It may be related to the PR I opened a days ago (kern/540
I think) but I'd like to know where the problem may lay.

and now :

ed0 1500 <Link>00.00.c0.4d.ed.08 38907 455 22603 1 8446
ed0 1500 FR-ATL-NET keltia.frmug.fr 38907 455 22603 1 8446
more than 5000 coll. in 4 minutes ? When you have only *2* machines on
the ethernet doing almost nothing except the backup ?? And more than
200 Ierrs as well.
Is there a problem in the SMC8013EP I got, in the driver or in
netstat's statistics ? I'm sure that I lose thoughput though.
Ideas anyone ?
