>Description:
The ethernet driver is having a lot of error on incoming packets.
Transfert between Keltia (FreeBSD-current) and Sidhe (Sparcbook 2) :

The error rate is high...
When doing a transfert from Keltia to Sidhe, the speed is better
(240 Kbps) but not lighting quick either. There are only the 2 machines
on the ethernet.

>How-To-Repeat:
FTP a file from/to Keltia shows this behaviour each time.
This behaviour seems new but I cannot garantee when it started :-(
>Fix:
Unknown unfortunately.
Open to suggestions, tests.
