You've got two issues here. The one causing the pfctl error is easy
to solve, you need to put a bandwidth keyword on the queue statement
(it can be 0Kb - it's ignored). The second, is that priority and
linkshare are mutually exclusive. If linkshare is in use, priority is
ignored. Use one or the other.
