Hello!
> The patch is as follows:
Seems, it should look like:
if (pmap_mode) {
for (; idx < TC_PRIO_MAX; idx++)
opt.priomap[idx] = opt.priomap[TC_PRIO_BESTEFFORT];
}
At least, it looks like this in my current tree. Please, check,
I do not remember that I tested it.
> band 1: highest priority - packets of type A up to 10% of link bandwidth.
> band 2: second highest priority - packets of type B up to 10% of link

> band 3: default priority: packets of type A and B over

> band 4: packets of type D. Lowest priority, no reserved bandwidth.

No. You may achive it only with classifier supporting multiple
policing filters. fwmark is the only one, which does not undesratnd them.
It is something sort of:
tc filter add ....... handle A fwmark classid 1 \
police rate <10%> burst 10K action continue
tc filter add ....... handle A fwmark classid 3
tc filter add ....... handle B fwmark classid 2
police rate <10%> burst 10K action continue
tc filter add ....... handle B fwmark classid 3 \
With default set to 4.
But fwmark will not eat this.
Try the following: mark all the packet but A and B with a third fwmark XXX
and make:
tc filter add ....... handle A fwmark classid 1 \
police rate <10%> burst 10K action continue
tc filter add ....... handle B fwmark classid 2 \
police rate <10%> burst 10K action continue
tc filter add ....... handle XXX fwmark classid 4
And set default to 3. Seems, it should work.
You may get the effect with CBQ, if create hierarchy sort of:
root-------|
| |
AB-|--| D
| | |
A B C
and tell him to reclassify exess packets from A and B to C
(look at cbqinit.eth1, it makes exactly this for RSVP,
class AB is :7FFF there, and class C is :7FFE.)
Then you replace "continue" with "reclassofy" in policers
setup above and that's all.
