      Add support for experimental networks on the control network. · df048b11
      Leigh B Stoller authored
      So what if your testbed has a control network but no experimental
      network? In the past you were SOL, but with this commit you can now
      create links and lans on the control network that look just like
      an experimental network link/lan.
      
      To make this work, ptopgen sports a new option (-C) that will put the
      control network links and wires and switches into the ptop file.
      
      libvtop generally operates as normal, but need to arrange for the
      physical ports to be put into dual tag/trunk mode, where the native
      vlan is the Control network. This is done with by setting attributes
      on the lan table entry that indicate dual and what to use for the
      native vlan. snmpit looks for these attributes.
      
      There are a couple of places that use the stack name (Control or
      Experiment) to determine if a vlan is control or experimental. This is
      not longer truu, and so need to use an attribute in the lan table
      entry. 
      
      The last bit of the puzzle is that snmpit has to be careful when
      disabling trunking on these ports. When this happens, all vlans are
      cleard from the ports (by the device layer), including the Control
      network itself, which would make the node unreachable. I had to add
      some special cases to watch for that, and return the ports to the
      control network.
      
      To turn this on, create a ControlNetVlans and enable it. The mapper
      looks for this and passes the -C argument to ptopgen.
      
      Nothing special in the NS file, except you have to turn on vlan
      encapsulation; tb-set-vlan-emulation vlan
      
      No delay nodes, but linkdelays work okay. Works for openvz containers
      as well.

      Whenever an experiment is using Vinterfaces, reserve the vlan tags · 545e72de
