====================
tc-testing: Add plugin for simple traffic generation

This series supersedes the previous submission that included a patch for test
case verification using JSON output.  It adds a new tdc plugin, scapyPlugin, as
a way to send traffic to test tc filters and actions.

The first patch makes a change to the TdcPlugin module that will allow tdc
plugins to examine the test case currently being executed, so plugins can
play a more active role in testing by accepting information or commands from
the test case.  This is required for scapyPlugin to work.

The second patch adds scapyPlugin itself, and an example test case file to
demonstrate how the scapy block works in the test cases.
