Re: [lwip-users] DHCP problems

[Trampas Stern]

OK walking through the code it appears somewhere along the way the ACD module was added and it looks like it needs to have it's timer periodically called. 

I added it to the timer list and seem to work now.  I would have figured that the ACD timer would have been called from the DHCP timer for backwards compatibility. I assume this was done for a good reason.
