Is it your opinion that it is possible to route 64 byte packets close to wire
speed with unmodified e1000e drivers? and unmodified kernel?

you might be able to tune ITR using ethtool -C ethx rx-usecs N
you may also want to increase or decrease the number of receive buffers using

Subject: [E1000-devel] [ixgbe] In RSS, I'd like to know algorithm that select
rx packet descriptor queue.
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.

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.

I CCd the maintainers list, which since you are talking about the out of
tree driver (I think) is probably more appropriate for future postings.

Wow, thanks Bill, that explanation was spot on, and very well put. Thanks for
taking the time to respond.

Luca, I'm a little confused. If it is the same TCP connection by

In the short term, you can always put the port into D3 using setpci (once the
driver is unloaded), which will take down the link if wake on is disabled.
Linux unfortunately doesn't have good device power management controls yet.
If you would like us to look into this feature as a feature reques
I believe that behavior is expected, 82575/576 don't support timestamp all as I
