one or more physical layer interfaces (PHYs);
one or more Media Access Controllers, each of the Media Access Controllers associated with one of the PHYs; and
one or more non-transitory machine-readable storage media comprising a plurality of instructions stored thereon that, in response to being executed, cause the network interface controller to:
in response to a power on reset, initialize a timer with a delay time for the one or more PHYs to delay configuration of the one or more PHYs for the delay time after the power on reset; and
after the delay time has expired, configure the one or more PHYs and the one or more Media Access Controllers.
