Re: [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

Got the board, done some basic testing: so far so good :)

The controller also supports MSI and (at least with my chipset - G965)
it works fine:

218: 80649 0 PCI-MSI-edge eth1

which is nice, otherwise it ends up sharing the IRQ with SATA and USB.

I also have a small patch:

Thanks for the patch. We'll add it for the next version.

FYI, TSO performance is _really_ bad; your tx speed will drop dramatically
with
TSO on (and it's on by default). I haven't yet been able to find the
problem.
If you want to improve tx performance, turn off TSO with ethtool.
