See https://wiki.freebsd.org/MIIBUS for initial information about the miibus driver that covers most PHYs supported by FreeBSD Ethernet devices. The miibus(4) man-page contains a list of devices that use this interface and which might be useful as examples for its use: https://www.freebsd.org/cgi/man.cgi?miibus(4) Regards, STefan
