[ECOS] IGMP and DHCP Gateway option 3

I try to send IGMP frame with eCos but my DHCP server didn't have the
Gateway option 3. Then I receive an error while I use a DHCP Server
without Option 3.

I didn't find in the documentation that we need this DHCP Option 3 to
send IGMP frame.

Does someone know something about IGMP and this DHCP Option 3 ?
because I don't understand why IGMP need a Gateway IP adress.
