error: while searching for:
A traffic generator used for functional testing, implemented with
`the Scapy library <https://scapy.readthedocs.io/en/latest/>`_.
The traffic generator uses an XML-RPC server to run Scapy on the remote TG node.
The traffic generator uses the :mod:`xmlrpc.server` module to run an XML-RPC server
in an interactive remote Python SSH session. The communication with the server is facilitated
with a local server proxy from the :mod:`xmlrpc.client` module.

========= BEGIN RPC FUNCTIONS =========
All of the functions in this section are intended to be exported to a python
shell which runs a scapy RPC server. These functions are made available via that
RPC server to the packet generator. To add a new function to the RPC server,
first write the function in this section. Then, if you need any imports, make sure to
add them to SCAPY_RPC_SERVER_IMPORTS as well. After that, add the function to the list
in EXPORTED_FUNCTIONS. Note that kwargs (keyword arguments) do not work via xmlrpc,
so you may need to construct wrapper functions around many scapy types.
"""
"""
Add the line needed to import something in a normal python environment
as an entry to this array. It will be imported before any functions are
sent to the server.
