It's based heavily on the example from pf.conf(5). But when I parse the rules with pfctl -nf /etc/pf.conf I am told:

# pfctl  -nf /etc/pf.conf
pfctl: the sum of the child bandwidth higher than parent "ssh"

It's because you haven't give any bandwidth for the ssh_interactive and ssh_bulk. If you dont, the first child queue get 100%, leaving nothing for the other. This was added in 3.6 somewhere - gave me som troubles too. Btw. try searching the archives another time, it has been discused before.
