I'm testing a 4 port 10G NIC (ixgbe) in a pci-e gen3 motherboard.

On most boots, all 4 ports show 5GT/s x8 bus, but on at least one boot,
two of the NICs came up as 5GT/s and x4.  It took a long time to notice this 
was the
problem that caused poor performance.

Is there a way in ethtool, or another standard-ish way to query
the bus speed and width?


Thanks,
Ben
