# dtsec(4)

Freescale Datapath Acceleration Architecture-based Three-Speed Ethernet Controller device driver

## NAME

**dtsec** – Freescale Datapath Acceleration Architecture-based Three-Speed Ethernet Controller device driver

## SYNOPSIS

To compile this driver into the kernel, place the following lines in your kernel configuration file:

**include "dpaa/config.dpaa"** **device dpaa** **device miibus**

## DESCRIPTION

The **dtsec** driver provides support for the DPAA-based gigabit Ethernet controller integrated in some of the Freescale system-on-chip devices.

The **dtsec** driver supports the following media types:

- autoselect

  Enable autoselection of the media type and options

- 10baseT/UTP

  Set 10Mbps operation

- 100baseTX

  Set 100Mbps operation

- 1000baseT

  Set 1000baseT operation

The **dtsec** driver supports the following media options:

- full-duplex

  Set full duplex operation

The **dtsec** driver supports two operating modes:

- Regular

  Normal mode, utilizing the full datapath acceleration, Buffer Manager, and Queue Manager.

- Independent

  Runs disconnected from the Buffer Manager and Queue Manager.

## HARDWARE

Gigabit Ethernet controllers built into the following Freescale system-on-chip devices are known to work with the **dtsec** driver:

- P2041, P3041

- P5010, P5020

Additionally, the following devices are expected to work, but are untested:

- P4080, P4040

- P5040
