Is anybody else seeing NDIS miniport large segment offload failing on W2K3
SP1 systems?
I have one system that has W2K3 SP1 RC2 and DO see large packets (64K) being
sent to a NDIS miniport. The same driver on W2K3 SP1 released version seems
to never use LSO. I’ve looked at two different NIC’s, that both support LSO,
and see the same thing.
I’ve also heard LSO doesn’t work on WXP SP2.
If others aren’t seeing this, I’ll need to dig some more.
I’m verifying this by using a software network sniffer (ethereal or MSFT’s
sniffer) and look at the packet trace. The send performance is also degraded
on the systems where LSO fails.
