    oh, thanks, I thought the interface names just depend on the used
    driver module.

    It is an onboard one:

    The I225-V are working fine, the other four make trouble.
    I am using transceiver modules AXS85-192-M3 from 10Gtek.

    As they work with kernel 5.x I assumed they are fine. 
    The allow_unsupported_sfp=1 does not make a difference. Shouldn't
    there be at least a syslog message if an unsupported sfp is
    detected?
