received packets, but you need to run a test which actually accesses
the data (usually not benchmarks)

Just FYI, our development tree is internal only for our out of tree driver, but
we send patches to the kernel ASAP, after they have passed testing.

Yes.
- Irq11 for eth0 is shared with uhci_hdc and dsppci2 because MSI is
unavailable.
- When the interrupt for either uhci_hdc or dsppci2 is asserted, we can see

I'm still evaluating RSS feature of Intel 82598EB AF 10G ethernet card.
I think this is my last problem.
that is computed hash value of NIC.
Before the evaluation, I wrote a simulation code to simulate ComputeHash
function according to datasheet.
and I checked
I don't think that can ever happen. The only useful case of this might be when
in VMDq mode and a broadcast packet was replicated to all the different VMs.

Wow, thanks Bill, that explanation was spot on, and very well put. Thanks for
