ovs-tcpdump: Add a tcpdump wrapper utility
Currently, there is some documentation which describes setting up and
using port mirrors for bridges. This documentation is helpful to setup
a packet capture for specific ports.
However, a utility to do such packet capture would be valuable, both
as an exercise in documenting the steps an additional time, and as a way
of providing an out-of-the-box experience for running a capture.
This commit adds a tcpdump-wrapper utility for such purpose. It uses the
Open vSwitch python library to add/remove ports and mirrors to/from the
Open vSwitch database. It will create a tcpdump instance listening on
the mirror port (allowing the user to specify additional arguments), and
dump data to the screen (or otherwise).
