I made efforts in that direction months ago, but found that it is very
messy to not first move all drivers to phylib, and then from phylib to
DM. To support all 3 is just gross and unwieldy.

It will. But for me it is better to move driver to DM and break FreeBSD
boot than removing ethernet driver.
Feel free to fix CONFIG_API and we can enable that option again.
