Hello,
is it possible that the number of bands for the PRIO qdisc is limited to 16?
tc qdisc add dev $DEVICE root handle 1: prio bands 16 priomap 1 2 2 2 1 2 0 0
1 1 1 1 1 1 1 1
succeeds but
tc qdisc add dev $DEVICE root handle 1: prio bands 17 priomap 1 2 2 2 1 2 0 0
1 1 1 1 1 1 1 1
returns: 'RTNETLINK answers: Invalid argument'
Is there any possibility to raise the number of bands to a higher value?
Thank you in advance.
I got a better error message than that -
"priomap" index > TC_PRIO_MAX=15
Greping for TC_PRIO_MAX shows it's in both kernel and iproute2's copy of
the headers - I don't know if you need to do both or not - but I would
and recompile kernel and tc
/include/linux/pkt_sched.h:#define TC_PRIO_MAX 15
