openbsd 数据包的列队和优先

针对内网的ip进行限速，使用openbsd pf 的数据包列队和优先可以实现吗？

在一个Queue中只能使用一种 调度器，在一个网络接口上面可以使用多个 queue 吗?

openbsd官方faq上为什么找不到列队和优先的相关内容 ？

pf queue changes PF has a new implementation of packet queueing - the configuration syntax is different to that used by altq. During a transition period, the old mechanism is still available by replacing "queue" keywords in /etc/pf.conf with "oldqueue". If instead you wish to switch to the new implementation, review the documentation in pf.conf(5).

举个例子：
queue name on vlan2 bandwidth 4M
queue testname parent name bandwidth 1M, min 500K, max 2M
queue othername parent name bandwidth 3M default
pass in on vlan2 from 10.0.2.0/24 set queue testname
成功设置这个网段的ip用户 带宽的限制


设置queue的思路 ,应该怎么理解？
