Hi!

We discovered a problem with the U-Boot DHCP client using the Windows 2000 DHCP Server. We have to use the Windows 2000 DHCP Server upon customer request!

The problem occurs when the IP-address of the DHCP-server is not equal to the IP-address of the TFTP-server. In the REQUEST-packet (client->server), the client uses the IP-address from the bootp-header (bp->siaddr - IP address of next bootstrap server) in the ServerID option (#54). This seems to be wrong (the Windows 2000 server doesn't respond with an ACK-packet)! The client has to use the IP-address sent by the server in the ServerID option from the OFFER-packet (server->client).

Please find attached a patch with our changes. This code runs without problems against the Windows 2000 DHCP-server and the Linux (Suse 8.0) DHCP-server.

Any comments/remarks? Anybody against commiting?

Best regards, Stefan Roese
