Re: [lwip-users] RFC: ARP Queueing

[Paul]

Hi all,

To get around the udp connection this is what I have done
create a master udp_pcbbound to IP_ADDR_ANY port 69. I have moved the 
source
ip address compare and source port compare into the udp_receive function.
In my receive function I now create a new udp_pcb, bind it to IP _ADDR_ANY
.port 0 and connect it to the incomming ip address and incomming port. I 
have now
got my tftp service working, although I havent got timeout supported yet.

I'll try and test and report on the cvs code later next week, if I have 
the time available.
