So in vmware you can specify that a port is to be used for trunking,
(and you do that by specifying a tag of 4095), but can't limit the list
of tags to allow - is that correct?
The parser (and the RNG) currently requires at least one <tag> element
in any <vlan> element. It sounds like we need to change that.
Kyle or Ansis - does it make sense for Open vSwitch to have a port
specified with trunk=yes and no list of specific tags?
Aside from this, you are interpreting the <vlan> element in portgroups,
but not the overlying <vlan> for the entire network (in practice this is
what would be used if no portgroup was chosen, and no vlan info came
from the domain's interface definition). If there isn't any practical
way to implement this, you should check for it and log a
CONFIG_UNSUPPORTED error if found.
