Log Message:
Add mue(4), driver for Microchip LAN75xx/LAN78xx known as internal NIC of
Raspberry Pi 3 B+, from OpenBSD.
Tested on Raspberry Pi 3 B+ (LAN7800) and Z-TEK ZE582 (LAN7500).
* BUGS/TODO
- If the media type is set to something other than 1000baseT-FDX, data
transmission becomes quite unstable. Also, ukphy(4) recognize 1000baseT as
a supported media type, but it is not in fact.
- Catch up with changes made to usmsc(4) in nick-nhusb branch, i.e.,
make the driver MP-safe.
- Support RX/VLAN/TX chekcsum offloading.

+.Nd Microchip LAN75xx/LAN78xx 10/100/Gigabit USB Ethernet device
+.Sh SYNOPSIS
+.Cd "mue* at uhub?"
+.Cd "ukphy* at mii?"
+.Sh DESCRIPTION
+The
+.Nm
+driver supports Microchip LAN7500/LAN7505/LAN7515/LAN7850 USB 2.0 Gigabit
+Ethernet devices and LAN7800/LAN7801 USB 3.0 Gigabit Ethernet devices,
+including the following:

+.It Raspberry Pi 3 Model B+
+.It Microchip EVB-LAN7800LC
+.It Z-TEK ZE582
+.El

+.Xr ifconfig 8
+.Sh HISTORY
+The
+.Nm
+device driver first appeared in
+.Ox 6.3 and
+.Nx 9.0 .
+.Sh AUTHORS
+.An -nosplit
+The
+.Nm
+driver was written by
+.An Kevin Lo Aq Mt ke...@openbsd.org
+for
+.Ox and ported to
+.Nx by
+.An Rin Okuyama Aq Mt r...@netbsd.org .
+.Sh 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.
