if the "--clientid" option is not passed to udhcp, udhcp will create a default client-id to pass to the server anyway. neither U-Boot nor the linux kernel pass a client-id in their dhcp requests. this means that in two common usage cases, usually involving tftp booting, or similar, the system will claim, and use, two different IP addresses during the course of booting: one allocated to the bootrom and/or the kernel, and one allocated to udhcp.
this patch differs from an earlier version sent to the mailing list in that current behavior is now preserved -- an explicit option now suppresses the default client-id.
