Hi !

   I write a app with OFP1.0, and the OpenFlow versions on OVS is *0x1:0x4*.
I want to set a flow on OVS:
*   "match=datapath.ofproto_parser.OFPMatch(nw_src=nw_src,nw_dst=nw_dst)"*

    the nw_src have been formatted to int with
    "*socket.ntohl(struct.unpack("!I",socket.inet_aton(srcip))[0])*"

     but on the ovs, the new added flow has no matching field(*no
nw_src/nw_dst*)

   what's wrong with it? does the formatting of nw_src cause influence or
any other reason?

     thanks!
