[lwip-devel] [patch #9169] Allows multicast packets through udp input layer

[Dirk Ziegelmeier]

Update of patch #9169 (project lwip):

                  Status:                    None => Invalid                
             Open/Closed:                    Open => Closed

Follow-up Comment #2:

Simply don't call udp_connect() and you will receive all multicast traffic on
that PCB automatically.

udp_connect() means: 
1) If I call udp_send() somewhere, it should go to the specified remote
address/port.
2) I _only_ want to receive from the specified remote IP address/port.


Note:
I'm currently thinking about reverting your last patch, because you can get
your desired behavior in this case by also not calling udp_connect() and
comparing the source IP as the first thing to do in your udp_recv() function.
