    Hello,

     

    The recommended workaround is to re-apply the TX pause configuration in software after hot-plug/link recovery. In practice, after the optical module is reinserted and the link comes back up, rewrite TX_PAUSE_EN (tx_pause_en, offset 0x122C[8:0]) because that register controls the TX PAUSE / TX PFC enable bits and can end up cleared.

     

    Regards,

we use SFP112 and DAC cable,   but it still fails to link up.
