This seems to have gotten lost, so I'll resend. Signed-off-by: Andy Fleming <afleming@freescale.com> * Added sysfs support to gianfar for modifying FIFO and stashing parameters * Updated driver to support 10 Mbit, full duplex operation * Improved comments throughout * Cleaned up and optimized offloading code * Fixed a bug where rx buffers were being improperly mapped and unmapped * (only manifested if cache-coherency was off) * Added support for using the eTSEC exact-match MAC registers * Bumped the version to 1.3 * Added support for distinguishing between reduced 100 and 10 Mbit modes * Modified default coalescing values to lower latency * Added documentation Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
