Follow-up Comment #3, bug #65581 (group lwip):
I happen to have an application that also sends multicast traffic. It does
bind() but also sets the socket option IP_MULTICAST_IF before calling
sendto(). That requires having LWIP_MULTICAST_TX_OPTIONS set.
That might be a more "standard" workaround than using
LWIP_HOOK_IP4_ROUTE_SRC.
