Re: [Cake] Multiple Hardware Queues

(sorry for the spam Toke, still getting used to a new email client)

Thanks for the input, this is pretty much the info I was hoping for.
At this point I'll probably swap out the dual port NIC I have with
something more reasonable and put the i350 to work where its
performance will actually be used.

Really excited to have cake support in upstream.

Looking at usage I noticed there were a few cake configuration
parameters I may have missed when setting up my sqm-scripts config.
Right now I'm just using the "piece-of-cake.qos" example, with my
interface config file as:

# Uplink and Downlink values are in kbps
UPLINK=23000
DOWNLINK=330000

# SQM recipe to use. For more information, see /usr/lib/sqm/*.help
SCRIPT=piece_of_cake.qos

# Optional/advanced config

#ENABLED=1
#QDISC=cake

#LLAM=tc_stab
#LINKLAYER=none
#OVERHEAD=0
#STAB_MTU=2047
#STAB_TSIZE=512
#STAB_MPU=0

#ILIMIT=
#ELIMIT=
#ITARGET=
#ETARGET=

# ECN ingress resp. egress. Values are ECN or NOECN.
#IECN=ECN
#EECN=ECN

# Extra qdisc options ingress resp. egress
IQDISC_OPTS="nat docsis ingress"
EQDISC_OPTS="nat docsis ack-filter"

# CoDel target
#TARGET=5ms

#ZERO_DSCP_INGRESS=1
#IGNORE_DSCP_INGRESS=1

With the result being:

I don't fully understand the docsis option, is it supposed to show up
under the tc qdisc show or is it all in the background? I'm just
worried I'm not setting this up properly.
