Well, I'm no DHCP expert either
Looking at the source and checking RFC-2131, REBOOTING state only needs
to verify an existing lease. That can be done by issuing a DHCPREQUEST
message with the known ip address.
Coherency suggests that given the address is correct, then the client
already has all necessary parameters correct, obtained from last request.
I would say the problem lies on that subject. Somehow that is not working.
Please post a network capture showing first DHCPREQUEST on startup and
then the link-down/link-up issue.
Please post a log with DHCP debugging (:#define DHCP_DEBUG LWIP_DBG_ON)
