Although it still is a possibility to use an external dhcp client, my
preference still goes to a small, internally coded dhcp client since you
won't add any dependencies. The reason I think it is quite easy is that I
don't want to implement it with a large feature set, we only have to send
two packets and receive two packets.
Currently I have the initial setup working, though the only problem that I
still have is that the source-address is still set wrongly for some reason
that I don't understand.
I have one eth0 device (with IP 192.168.1.98) and the new eth1 device
(which is rndis0, but renamed). When I create the needed UDP packets to
send on eth1 with source 0.0.0.0 to 255.255.255.255, I still see with
tcpdump that the source address of the package on the eth1 device is for
some reason 192.168.1.98. After I have figured this tiny detail out, it
should be quite straight forward to implement the DHCP client.
Furthermore, if I change the code within odccm, not to use dhcp for eth1,
but as a test for eth0, I do get a valid reply from my router. So the DHCP
code is working as it should ;)
When I have more information, I will let you guys know.
