The mue device driver first appeared in OpenBSD 6.3 and NetBSD 9.0.
The mue driver was written by Kevin Lo <firstname.lastname@example.org> for
OpenBSD and ported to NetBSD by Rin Okuyama <email@example.com>.
If the media type is set to other than 1000BASE-T full-duplex, data
transmission becomes quite unstable. Also, ukphy mistakenly recognizes
1000BASE-T half-duplex as a supported media type, although the adapters
do not support it.
