      net: SO_RCVMARK socket option for SO_MARK with recvmsg() · 6fd1d51c
      Erin MacNeil authored
      Adding a new socket option, SO_RCVMARK, to indicate that SO_MARK
      should be included in the ancillary data returned by recvmsg().
      
      Renamed the sock_recv_ts_and_drops() function to sock_recv_cmsgs().
