The Intel 82599 series of 10G Ethernet controllers has a bit-banged SPI interface that's register-compatible with the one in the 1G controllers, except the register addresses are shifted up by 0x10000. See http://www.intel.com/content/www/us/en/ethernet-controllers/82599-10-gbe-con....
I tested this with a board that has the 0x10fc device and a Micron M25P40 SPI flash chip. I filled in device IDs for other 82599 devices per https://www-ssl.intel.com/content/www/us/en/ethernet-controllers/82599-10-gb... and lifted the name strings from the PCI SIG device ID registry.

Hello Ed,
thank you very much for this patch. I have made some small refinements to the names and added a few other PCI IDs that seem to make sense (and actually exist). I have committed the result in r1856.
