I tested it with two ports on a 13.2p3 box with the port intel-ix-kmod
in version 3.3.35 and the ports behave like you have observed:

ix<n> NICs with SFP+ cage display the optics info, if available.
ix<n> NICs with copper-port have approx. 0.4s delay.

I guess that the driver should know if a certain model of the
NIC has a SFP+ cage with some i2c bus -- and if it's copper-only, it
should not query the bus.
