Follow-up Comment #16, task #14247 (project lwip):

Sorry for not being clear enough :-)
Yes, we would need the check in recv_udp. And we would need the netconn->flag
for LWIP_NETBUF_RECVINFO (!=0). But we would store the info only if the flag
PKTINFO is enabled in the netconn.
And that could be enabled by default to leave netconn behaviour as it was, and
be disabled for sockets. But in the end, it's probably good enough to just
disable it by default for all netconns & sockets and provide an API to enable
