ALTQ cbq(efficient) in OpenBSD 3.3

[Mark Bojara <mark@mics.co.za>]

Hello All,

Ive set up OpenBSD to run ALTQ and it works very nice (alot better than
freebsd.. but freebsd is still be prefered OS). With ALTQ on FreeBSD I
could use the option efficient wich when I enabled this option it would be
able to use full bandwidth from its parent if borrowing was enabled.

Basically I have to classes under one parent. I wont both classes to get
gaurenteed bandwidth but if the other class is not using its bandwidth it
can be used by the class requesting it.

Current Setup:

altq on dc0 cbq bandwidth 100% queue { std_uplink, local_uplink }
queue std_uplink        cbq(default)
queue local_uplink      bandwidth 256Kb { jobsd_uplink, joxp_uplink }
 queue jobsd_uplink             cbq(borrow) bandwidth 128Kb
 queue joxp_uplink              cbq(borrow) bandwidth 128Kb

altq on rl0 cbq bandwidth 100% queue { std_hosting, local_hosting }
queue std_hosting       cbq(default)
queue local_hosting     bandwidth 256Kb { jobsd_hosting, joxp_hosting }
 queue jobsd_hosting            cbq(borrow) bandwidth 128Kb
 queue joxp_hosting             cbq(borrow) bandwidth 128Kb
