RE: [ECOS] DHCP w/ Win2K server?

["Dan Conti" <danc at iobjects dot com>]

I think we saw this at one point. IIRC (it's been a while), the eCos
DHCP client assumes a gateway will be returned, and with linux dhcp
servers one is returned by default, but on win2k it isn't. I believe it
says in the spec that you actually are supposed to request a gateway
server ip if you want one, making this an eCos bug?

In net/tcpip/current/src/lib/dhcp_prot.c, around line 596 (in case
DHCPSTATE_REQUESTING), try adding the following line:

	    set_fixed_tag( xmit, TAG_DHCP_PARM_REQ_LIST, TAG_GATEWAY, 1
);

to add the gateway request to the DHCP packet. I dont know if there is a
way to adjust the win2k dhcp server configuration to automagically give
this out though.
