# qec(4)

SPARC64 Quad Ethernet Controller

## NAME

**qec** – SPARC64 Quad Ethernet Controller

## SYNOPSIS

**qec\* at sbus?** **be\* at qec?** **qe\* at qec?**

## DESCRIPTION

The **qec** driver is an SBus controller that can contain either one [be(4)](/be/4.md) Ethernet controller (Sun part number SUNW,501-2655) or four [qe(4)](/qe/4.md) Ethernet controllers (Sun part number SUNW,501-2062). This driver, like other buses, is not directly available to users. In essence it is a buffering DMA controller.

## SEE ALSO

[be(4)](/be/4.md), [intro(4)](/intro/4.md), [qe(4)](/qe/4.md), [sbus(4)](/sbus/4.md)

## HISTORY

OpenBSD support for the **qec** first appeared in OpenBSD 3.0.
