183 * The MX51 3stack board seems to have a hardware "peculiarity" confirmed under
184 * U-Boot, RedBoot and Linux: the ethernet Rx signal is reaching the CS8900A
185 * controller inverted. The controller is capable of detecting and correcting
186 * this, but it needs 4 network packets for that. Which means, at startup, you
187 * will not receive answers to the first 4 packest, unless there have been some
188 * broadcasts on the network, or your board is on a hub. Reducing the ARP
189 * timeout from default 5 seconds to 200ms we speed up the initial TFTP
190 * transfer, should the user wish one, significantly.
