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