    I've encountered some issues with disabling flow control on this card. I edited boot.conf.local to include dev.ix.0.fc=0, but it didn't solve the problem.

    I also tried using system tunables in the same manner, but without success. Every time the system boots, it displays:

    media: Ethernet autoselect (10Gbase-T <full-duplex,rxpause,txpause>)
    

    However, if I navigate to System/Advanced/System Tunables and press "edit" on the relevant system tunable, then save and apply without making any changes, it changes to:

    media: Ethernet autoselect (10Gbase-T <full-duplex>)
    

    What am I doing wrong, and how can I resolve this issue?

      I assume you're checking ix0?

      Try setting: hw.ix.flow_control=0
