127 * The MX31ADS board seems to have a hardware "peculiarity" confirmed under
128 * U-Boot, RedBoot and Linux: the ethernet Rx signal is reaching the CS8900A
129 * controller inverted. The controller is capable of detecting and correcting
130 * this, but it needs 4 network packets for that. Which means, at startup, you
131 * will not receive answers to the first 4 packest, unless there have been some
132 * broadcasts on the network, or your board is on a hub. Reducing the ARP
133 * timeout from default 5 seconds to 200ms we speed up the initial TFTP
134 * transfer, should the user wish one, significantly.
