Other registers reset when the ECR[ETHER_EN] bit is cleared (which is accomplished by a hard reset or
software to halt operation). By clearing ECR[ETHER_EN], configuration control registers such as the
TCR and RCR are not reset, but the entire data path is reset.

You need to initialize portions the FEC prior to setting the ECR[ETHER_EN] bit. The exact values depend
on the particular application. The sequence is not important.
