  SrcAddress

  The IP source address for a sender host. Must be non-zero.

  SrcPort

  The UDP/TCP source port for a sender, or zero to indicate `none'.

  Flow Label

  A 24-bit Flow Label, defined in IPv6. This value may be used by the packet classifier to efficiently identify the packets belonging to a particular (sender->destination) data flow.
