The tsec driver provides support for the three-speed Ethernet controller (TSEC) found on the Freescale MPC8349E processor family. It uses an external PHY or an internal 10-bit interface.

The tsec driver supports several media types, which are selected via the ifconfig(8) command. The supported media types are:
