Follow-up Comment #14, task #14247 (project lwip):
The SOF_PKTINFO flag is better off in struct netconn anyway. It is not used in
core code at all.
Given that we could:
- make it NETCONN_FLAG_PKTINFO
- leave LWIP_NETBUF_RECVINFO as it was
- enable NETCONN_FLAG_PKTINFO for netconns (add a function/define for that!)
- disable NETCONN_FLAG_PKTINFO for sockets
- enable NETCONN_FLAG_PKTINFO if enabled via setsockopt(IP_PKTINFO)
- output PKTINFO if the netbuf has that information
