[ovs-dev] Network namespace support for OpenVSwitch

[Justin Pettit]

Ben and I talked about this briefly.  It won't currently work with the kernel datapath, but it probably wouldn't be too bad to add support.  For the time-being, would the user-space datapath work for you?  With that, you could specify different "netdev" datapaths.  Obviously, there would be a bit of a performance impact, but it may be good enough to at least start testing.  (Note that the user-space datapath is only available in "unstable" releases, such as the just released 0.99.0.)
