126 * controller inverted. The controller is capable of detecting and correcting
127 * this, but it needs 4 network packets for that. Which means, at startup, you
128 * will not receive answers to the first 4 packest, unless there have been some
129 * broadcasts on the network, or your board is on a hub. Reducing the ARP
130 * timeout from default 5 seconds to 200ms we speed up the initial TFTP
131 * transfer, should the user wish one, significantly.
