> If it has an SFP+, won't the it be LR or SR depending on the type of > SFP+ installed? 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+. Steinar Haug, Nethelp consulting, sthaug@nethelp.no
