AFAIK the list is: ix, ixl, bnxt, myx, mcx, mvneta

BTW 10Gb NICs also support 1Gb SFPs and the diagnostics work fine (and
are often easier to get hold of than 1G fibre NICs).

# ifconfig ixl2 sff
        lladdr f8:f2:1e:57:46:82
        index 3 priority 0 llprio 3
        media: Ethernet autoselect (1000baseLX full-duplex,rxpause,txpause)

        model: FLEXOPTIX S.1312.10.D rev A

That's the default used by em if another media type can't be worked out,
I'm not sure if full information on this is actually available from the
NIC (at least without adding sff diagnostics to em(4) too - and that
would be done outside of the "media" mechanism).
