(In reply to mario felicioni from comment #2)
well, I'll try. There's nothing difficult here, except for this one:
If IP_PKTINFO is passed to sendmsg(2) and ipi_spec_dst is not zero, then it is
used as the local source address for the routing table lookup and for setting
up IP source route options.  When ipi_ifindex is not zero, the primary local
address of the interface specified by the index overwrites ipi_spec_dst for the
routing table lookup.
Perhaps I will omit this.
