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).
