The card is *sold* and *advertised* by Intel as a 10GBase-LR card. It
may well be the case that it would also work with a 10GBase-SR SFP+.
I don't have one of these lying around to test, unfortunately. But I
have indeed verified that the SFP+ in the card is a 1310 nm 10GBase-LR
unit (specifically it's a Finisar FTLX1471D3BCV).
As such, I believe the ixgbe code should either set the card type as
10GBase-LR (statically), since that's how the card is sold/delivered.
Or it should include code to read the optics type from the SFP+.
