++ Application changes:
|
||||||
|
|
||||||
|
* UDP does NOT receive multicast traffic from ALL netifs on an UDP PCB bound to a specific
|
||||||
|
netif any more. Users need to bind to IP_ADDR_ANY to receive multicast traffic and compare
|
||||||
|
ip_current_netif() to the desired netif for every packet.
|
||||||
|
See bug #49662 for an explanation.
