+		CONFIG_BOOTP_DHCP_REQUEST_DELAY
+
+		A 32bit value in microseconds for a delay between
+		receiving a "DHCP Offer" and sending the "DHCP Request".
+		This fixes a problem with certain DHCP servers that don't
+		respond 100% of the time to a "DHCP request". E.g. On an
+		AT91RM9200 processor running at 180MHz, this delay needed
+		to be *at least* 15,000 usec before a Windows Server 2003
+		DHCP server would reply 100% of the time. I recommend at
+		least 50,000 usec to be safe. The alternative is to hope
+		that one of the retries will be successful but note that
+		the DHCP timeout and retry process takes a longer than
+		this delay.
