Add options for auto MAC and ARP setup.
Auto MAC setup sets each host MAC equal to its DPID, which simplifiesdebugging.
Auto ARP setup removes the need for broadcast support for ARP, whichenables a smaller NOX controller.
Make Ripcord-specific topologies optional
If ripcord.dctopo imports properly, then include its topologies in thelist of available ones. Also replace topo.py with new generictopologies and update paths.
Support more topologies
Add iperf UDP test
Add xterm support
Separate kernel and user switches into separate objects
Enable controller-less setups
Add more NOX options
Restore iperf test
Also simplify test running.
Remove/merge obsolete examples
Add mn_run.py, a script to run Mininets.
Simplifies launching a Mininet or running tests on one.
