I actually don't, but I assume that demand for queues will quickly increase once 
the feature becomes available. e.g. in e1000 hardware (pci-e) we support 2, and 
this is really old hardware already (laugh), 82575 has 4.

the ixgbe driver me and Ayyappan posted already supports 64 rx queues and 32 tx...

I can only expect the next generation to take a bigger jump and implement at 
least 128 queues... :)
