Godo to hear.

One thing I'd like to see people who have ixgbe hardware (X550 and anything 
else) is RSS. A good smoke test is to open up a high-traffic TCP stream between 
the ixgbe box and another, with the ixgbe box being the receiver. A tool for 
this is iperf.

In another window, watch interrupt count for ixgbe using 'intrstat 1' - you 
should see a ton of interrupts from ixgbe landing on one particular CPU.

Then, open up a second (or third, or fourth) such stream and you should see the 
interrupts for those land on a different CPU, as show with intrstat.

Since receive-side scaling was one of the major areas I had to re-work to 
accommodate X550, this basic test would be a quick (albeit not exactly 
scientific) way of making sure it's working as intended.
