ostinato.protocols.icmp_pb2 module

To add and configure Icmp in a stream, add a protocol to the stream, set the protocol id to ost_pb.Protocol.kIcmpFieldNumber and access the Icmp object from the Protocol object's Extensions dictionary using the key icmp_pb2.icmp

from ostinato.protocols import icmp_pb2
...
# stream is an object of type ost_pb.Stream
proto = stream.protocol.add()
proto.protocol_id.id = ost_pb.Protocol.kIcmpFieldNumber
my_icmp = proto.Extensions[icmp_pb2.icmp]

You can then set Icmp attributes using my_icmp.<attribute>
