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