  Andrew and others,

  what do you think about using a flags fielf + union field for
different kinds of glue? I mean that if_vlantrunk, if_trunk, if_bridge
and may be some future glues are mutually exclusive.

If we put them under one union and add an integer field that identifies
what is stored in the union, then we will:

1) keep the structure smaller
2) structure won't grow in future, when adding more glues
3) easier to avoid bugs like attaching to bridge and vlan trunk
   simultaneously
