You cannot force speed with ix, only force autoneg. You need to use the adv=
ertise_speed sysctl for this:

sysctl -d dev.ix.0.advertise_speed
dev.ix.0.advertise_speed:
Control advertised link speed using these flags:
        0x1 - advertise 100M
        0x2 - advertise 1G
        0x4 - advertise 10G
        0x8 - advertise 10M

        100M and 10M are only supported on certain adapters.

I just inserted a 10G transceiver into port 8. It shows up as a 10GBase-SR

At the same time, on the server side, ifconfig indicates:

        status: no carrier
        supported media:
                media autoselect
                media 10Gbase-SR
        nd6 options=3D23<PERFORMNUD,ACCEPT_RTADV,AUTO_LINKLOCAL>
        plugged: SFP/SFP+/SFP28 10G Base-SR (LC)
        vendor: AVAGO PN: AFBR-703SDZ SN: AD0946A00YB DATE: 2009-11-10
        module temperature: 36.75 C Voltage: 3.32 Volts
        RX: 0.67 mW (-1.72 dBm) TX: 0.56 mW (-2.46 dBm)

I have not yet tried moving from auto-negotiate on both ends.
