Driver for Intel 10GbE adapter

[Greg Rivers]

I'm trying to light an Intel 10GbE adapter in an HP DL380 G5 using very 
recent 7.1-STABLE amd64 with GENERIC kernel.  I expected the ixbg(4) 
driver to attach, but it does not.

The labels on the card show:
 	INTEL(R) 10GbE XF SR 2 PORT SERVER ADAPTER
 	893135
 	EXPX9502FXSRGP5

 	001B211170BE 028AD E15728-003


A verbose boot shows the card on the PCI bus, but no driver attaches:

pciconf shows:

I thought perhaps it would be a simple matter of adding/updating a card ID 
in the driver header file, but I see that sys/dev/ixgb/ixgb_ids.h already 
contains an entry for 0xA15F as listed above.

Does anyone have experience with this card or know how to get it to probe 
and attach?  Thanks!
