# ukphy(4)

generic/unknown IEEE 802.3u Ethernet PHY

## NAME

**ukphy** – generic/unknown IEEE 802.3u Ethernet PHY

## SYNOPSIS

**ukphy\* at mii?**

## DESCRIPTION

The **ukphy** driver supports the basic functionality of most Ethernet PHYs.

## SEE ALSO

[ifmedia(4)](/ifmedia/4.md), [intro(4)](/intro/4.md), [mii(4)](/mii/4.md), [ifconfig(8)](/ifconfig/8.md)

## CAVEATS

In areas where the programming interface for PHYs differ, such as detecting the currently active medium, this driver often does not work optimally. When available, it is best to use a PHY-specific driver.
