[Bug 19493] New: socket option IP_PKTINFO is not implemented

http://bugs.winehq.org/show_bug.cgi?id=19493

Summary: socket option IP_PKTINFO is not implemented
           Product: Wine
           Version: 1.1.12
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winsock
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

The socket option IP_PKTINFO is not implemented:

the source code
  setsockopt(fd,IPPROTO_IP,IP_PKTINFO,(const char*)(&yes),sizeof(int));
gives the error
  fixme:winsock:WS_setsockopt Unknown IPPROTO_IP optname 0x00000013

This prevents a multicast client from distinguishing the incoming multicast
packets by their multicast group.
