Long ago re_diag() code was disabled by default(rev 1.68). So I think
you should never see the "diagnostic failed" message on FreeBSD.
The other odd thing I see from your demsg output is ukphy(4)
attachment. If you boot system with bootverbose mode ukphy(4) would
have printed PHY OID and model number. Please let me know the
OID/model number. I guess it should use rlphy(4).
(If you should use NetBSD you may need to define MIIVERBOSE to active
verbose message.)
