HISTORY
The mue device driver first appeared in OpenBSD 6.3 and NetBSD 9.0.

AUTHORS
-nosplit The mue driver was written by Kevin Lo <kevlo@openbsd.org> for OpenBSD and ported to NetBSD by Rin Okuyama <rin@netbsd.org>.

BUGS
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.
