SFQ external classifier baseclass purpose

["Dzmitry Shykuts" <dshykuts@xxxxxxxxxxxxxxxxxxx>]

Hello!

Have a traffic shaping rules. What is the right baseclass: 1:11 and 1:12 or
1:1 or other?

        # Add discuiplines for DL device
        tc qdisc add dev $devDL root handle 1: htb default 12

        # Add classes for DL device
        tc class add dev $devDL parent 1: classid 1:1 htb rate $bwDL ceil
$bwDL quantum $quantum
        tc class add dev $devDL parent 1:1 classid 1:11 htb prio 1 rate
$bwPrivateDL ceil $bwDL quantum $quantum
        tc class add dev $devDL parent 1:1 classid 1:12 htb prio 2 rate
$bwPublicDL ceil $bwPublicDL quantum $quantum

        tc qdisc add dev $devDL parent 1:11 handle 11: sfq divisor $divisor
perturb $perturb
        tc qdisc add dev $devDL parent 1:12 handle 12: sfq divisor $divisor
perturb $perturb

        tc filter add dev $devDL protocol all prio 1 parent 11: handle 11
flow hash keys dst divisor $divisor baseclass 1:11
        tc filter add dev $devDL protocol all prio 2 parent 12: handle 12
flow hash keys dst divisor $divisor baseclass 1:12

        # Add filters for DL device
        if [ -s $filePrivate ]; then
            for ip in `grep -v "#" $filePrivate`; do
                if [ `expr index $ip :` = 0 ]; then
                    tc filter add dev $devDL protocol all prio 1 parent 1:
u32 match ip dst $ip flowid 1:11
                else
                    echo $ip
                    tc filter add dev $devDL protocol all prio 1 parent 1:
u32 match ip6 dst $ip flowid 1:11
                fi
            done
        fi

        tc filter add dev $devDL protocol all prio 2 parent 1: u32 match ip
dst 0/0 flowid 1:12
        tc filter add dev $devDL protocol all prio 2 parent 1: u32 match ip6
dst ::/0 flowid 1:12

P.S. By default, if not specified, baseclass defined as 11:1 and 12:1.
