Hi Bernd,

I just ordered both a PCI-X and a PCI-e version of the Intel PRO/1000 MT
adapters. After a bit of googling, it would appear that Broadcom has a
tool called BACS that can be used to disable the LSO support feature of
Netxtreme cards. I'm not sure if this is the right version for your
particular adapter. The version.txt file says it supports Vista but not
Windows 7. I would give it a try anyway as Vista and Windows 7 are very
similar OS's ...

I'm interested in fixing this issue. But I would feel more motivated to
make this a high priority if you can verify that the client also works
well with a Netxtreme adapter that has the LSO feature disabled. If so,
fixing the Intel card LSO issue should also have a high probability of
resolving your Broadcom Netxtreme issue as well.


A bit more information on BACS and LSO options ...

Hi Matthew,

the BACS tools doesn't complain about Win7, it shows me that my adapter is LSO capable and that it receives a lot of LSO requests but unfortunately there is no option to switch LSO off in the advanced configuration tab.

I very much appreciate your effort to solve this problem!

Regards,

Bernd
