[U-Boot] [PATCH] DHCP: fix dhcp command parameters overwrite issue

[Wolfgang Denk]

Dear Bo Shen,

In message <1336036915-6422-1-git-send-email-voice.shen at gmail.com> you wrote:

This behaviour is not a bug, it is intentional.  If the DHCP server
returns any network configuration parameters, thise shall take
precedence over any user-defined (default-) settings.

If you want to ignore the boot filename returned by the DHCP server,
you can do so: set autoload to no, use DHCP to get the (rest of) the
network configuration, and then use tftp to download the boot file of
your choice.  Similar for any other network parameters returned by the
DHCP server.

We had a similar discussion not so long ago; please see here for
reference:

Thanks for your patch, but we will not apply it, as the current
behaviour is correct (or at least as intended).

Best regards,

Wolfgang Denk
