[PATCH 1/1] actions: keyword flowid or classid terminates action pipeline

From: Jamal Hadi Salim <jhs@mojatatu.com>

scenario testcase:

TC="sudo ./tc/tc"
DEV="dev eth0"
$TC qdisc del $DEV ingress
$TC qdisc add $DEV ingress
$TC filter add $DEV parent ffff: protocol ip u32 match ip src 10.0.0.0/24 action police rate 6Mbit burst 6Mbit drop flowid :1
$TC filter add $DEV parent ffff: protocol ip u32 match ip dst 10.0.0.0/24 action police rate 1Gbit burst 1Gbit pass flowid :1
$TC -s filter ls $DEV parent ffff: protocol ip
$TC qdisc del $DEV ingress
$TC qdisc add $DEV ingress
$TC filter add $DEV parent ffff: protocol ip u32 match ip src 10.0.0.0/24 flowid 1:1 action police rate 6Mbit burst 6Mbit drop
$TC filter add $DEV parent ffff: protocol ip u32 match ip dst 10.0.0.0/24 flowid 1:2 action police rate 1Gbit burst 1Gbit pass

$TC -s filter ls $DEV parent ffff: protocol ip
$TC qdisc del $DEV ingress
$TC qdisc add $DEV ingress
$TC filter add $DEV parent ffff: protocol ip pref 10 \
u32 match ip protocol 1 0xff \
flowid 1:10 \
action skbedit mark 11 \
action police rate 10kbit burst 10k pipe index 1 \
action skbedit mark 12 \
action police rate 20kbit burst 20k pipe index 2 \
action mirred egress mirror dev dummy0

$TC -s filter ls $DEV parent ffff: protocol ip
$TC qdisc del $DEV ingress
$TC qdisc add $DEV ingress
$TC filter add $DEV parent ffff: protocol ip pref 10 \
u32 match ip protocol 1 0xff \
action skbedit mark 11 \
action police rate 10kbit burst 10k pipe index 1 \
action skbedit mark 12 \
action police rate 20kbit burst 20k pipe index 2 \
action mirred egress mirror dev dummy0 \
flowid 1:10

$TC -s filter ls $DEV parent ffff: protocol ip
