problem in saving stream as python script for unimplemented protocols like GRE, MPLS...

[nmchowdary]

I am importing PCAP file having MPLS protocol, as MPLS protocol is not available, ostinato treats MPLS as a hexdump and it is decoding layers above MPLS properly.
Through ostinato GUI i am able to send packets properly and in wireshark capture i am be able to see all the headers including MPLS properly.
But when i save it as python script, MPLS header is dumped as hex field and content for that field is exported as empty.(snippt of python script pasted below )

p.protocol_id.id = ost_pb.Protocol.kHexDumpFieldNumber
p.Extensions[hexDump].content = ''
p.Extensions[hexDump].pad_until_end = False

Note : same problem observed for all unimplemented protocols like GRE, GTP...
