+         BOOTP packets are uniquely identified using a 32-bit ID. The
+         server will copy the ID from client requests to responses and
+         U-Boot will use this to determine if it is the destination of
+         an incoming response. Some servers will check that addresses
+         aren't in use before handing them out (usually using an ARP
+         ping) and therefore take up to a few hundred milliseconds to
+         respond. Network congestion may also influence the time it
+         takes for a response to make it back to the client. If that
+         time is too long, U-Boot will retransmit requests. In order
+         to allow earlier responses to still be accepted after these
+         retransmissions, U-Boot's BOOTP client keeps a small cache of
+         IDs. The CONFIG_BOOTP_ID_CACHE_SIZE controls the size of this
+         cache. The default is to keep IDs for up to four outstanding
+         requests. Increasing this will allow U-Boot to accept offers
+         from a BOOTP client in networks with unusually high latency.
