++This file describes a patch to use version 1.2 of the ethernet driver
++for Intel Ixp4XX with Linux 2.6 kernels.
++
++Authors/History
++---------------
++
++This patch is based on the nslu2-linux project's patches for version
++1.1 of the same driver. The changes were adapted to version 1.2 by
++Hannes Reich & Cian Masterson.
++
++Status
++------
++
++This code has been tested on a Linksys NSLU2. It works in big-endian
++mode, performance seems around 10% faster than 1.4.
++
++The code does not work in little-endian mode. It appears as though the
++hardware is initialised correctly, but packet receive / transmit done
++callbacks are never called.
++
++The driver has not been tested in "polling mode".
++
++Licence Information
++-------------------
++
++This patch is licenced under the same terms as the original Ethernet
++driver (GPL v2).
++
++References
++----------
++
++The nslu2-linux project's patch for version 1.1 of the driver is at
++http://nslu.sourceforge.net/downloads/ixp425_eth.c.patch
