Hi Alex,
I was looking for the SIOCGI2C socket ioctl API, and did not find it in the=
intel driver. Which led me to believe this was the reason for me not seein=
g the SFP data.
But after correctly looking up the SFP info (the port was in a different j=
ail, which confused me), it turns out that it's not Intel NIC, but Qlogic C=
NA who are not providing this info when in IP mode.

Hi Richard,
which Intel nics you're referring to? IIRC ixgbe/ixl SIOCGI2C support was a=
dded 5? years ago.
