Ok, so I will discuss the ixgbe patch with Jeff :)

Ben, on the ethtool side, attached is a patch to enable the following
option and output; It's still missing externally calibrated optics
support (my current one is internally calibrated, so that's difficult
to test anything). What do you think ? Is there any other data that
could be interesting to show with -O or -m options ?

I based the text output on Juniper's, which is quite parsable by other
apps, but if someone sees a more appropriate output mode, let me know.
