Hi Jason,

patch is related to a network driver, so Ben should be informed, too.

If all supported processors implement the same way, we do not need to
distinguish. The comment does not add any further info.

Not sure. Why is this call removed ? We have changed the storage for the
MAC address, but we need always to set the FEC controller. What is the
reason to drop it ?
