This is great news, you will be hearing from me. Thanks for the offer!

I have put both up-to-date em and bge patches on the site. em(4) extracted=
=20
from Pyun YongHyeon's post to the ALTQ-ML and bge(4) from the rofug.ro=20
patchset.
If possible test all the tree major disciplines (PRIQ, CBQ and HFSC) with a=
=20
fully open pipe (i.e. bandwidth =3D 1Gb) and a fairly restricted (child) qu=
eue.=20
Push some traffic through and see if you get the bandwidth you asked for=20
(mind you that pf takes *BIT not *BYTE).
Best test scenario is something like:
Server1(ALTQ) ---[switch]------ Client1
|
+---------- Client2
On Server1 you have a full default queue (=3D1Gb or a bit less) and a small=
er=20
child queue[1]. Then you make the the big one the default and force traffic=
=20
to Client2 through the small one[2]. Then start a download from both client=
s.=20
If that works well (check $pfctl -vvsq output to see dropping in effect) yo=
u=20
should redefine the small queue to borrow from the parent[3]. With that in=
=20
effect you start a singel download from Client2 (where you should have full=
=20
speed now). Then if that works as it should you start downloading from=20
Client1 again and should have the same situation as before (w/o borrow in=20
place).
[1] altq on $ext_if bandwidth 1Gb cbq queue { dflt }
queue dflt bandwidth 100% cbq(default) { small }
queue small bandwidth 5% cbq
[2] pass out on $ext_if from any to client2 queue small
[3] queue small bandwidth 5% cbq(borrow)
NOTE: Always disable and reenable pf after changing altqs or they will not =
be=20
setup properly:
$ pfctl -Fa -d; pfctl -ef pf.conf
=2D-=20
