step1 : e1000e 82574L connected to embedded device whose nic speed 100M by poe power.
step2: e1000e connected to embedded device whose nic speed 1000M by poe power.
whiel(1)
{
step1;
step2;
}
and then, it link with 1000M device by power, can't Tx and Rx.
it try to send a frame, it's led will be blink like a frame pass it.
link partner send a frame to it, led will be blink as like a frame by received. but MAC not

received it.

set link portner's speed as 100M, communitation is ok.

    What OS are you running? We would also need the kernel version, driver version, and hardware details. Also, what hardware is the link partner?

    Thanks.

    Have you been able to reproduce this issue with the POE adapter removed? Have you confirmed that the POE adapter is compatible with 1000BASE-T?
