- * RTEMS/TCPIP driver for MCF5272 Ethernet
- *
- * Modified for MPC860 by Jay Monkman (jmonkman@lopingdog.com)
- *
- * This supports Ethernet on either SCC1 or the FEC of the MPC860T.
- * Right now, we only do 10 Mbps, even with the FEC. The function
- * rtems_enet_driver_attach determines which one to use. Currently,
- * only one may be used at a time.
- *
- * Based on the MC68360 network driver by
- * W. Eric Norum
- * Saskatchewan Accelerator Laboratory
- * University of Saskatchewan
- * Saskatoon, Saskatchewan, CANADA
- * eric@skatter.usask.ca
- *
- * This supports ethernet on SCC1. Right now, we only do 10 Mbps.
- *
- * Modifications by Darlene Stewart <Darlene.Stewart@iit.nrc.ca>
- * and Charles-Antoine Gauthier <charles.gauthier@iit.nrc.ca>
