Support for Freescale integrated Three-Speed Ethernet Controller (TSEC).

TSEC is the MAC engine offering 10, 100 or 1000 Mbps speed and is found on different Freescale parts (MPC83xx, MPC85xx). Depending on the silicon version there are up to four TSEC units integrated on the chip. This driver also works with the enhanced version of the controller (eTSEC), which is backwards compatible, but doesn't take advantage of its additional features (various off-loading mechanisms) at the moment.
