SubjectRe: [PATCH 0/4] atl1: Revised Attansic L1 ethernet driver


I've got the p5B-E board to with the onboard attansic l1.

I did the the atl1-2.0.2 patch against the 2.6.19.rc6 kernel.

I can confirm the card is working but performance is *really* bad, 200Kb/s
over Gbit LAN.
I tried copying a ~50MB file over SSH and it didn't complete because of a
connection stall.

I also tried turninig off TSO as adviced, but i got the message "operation
not supported".

Im willing to do more testing, just tell me what I can do.

Greetings
Vasco
