Subject: [PATCH 1/1] iproute2: rsvp classifier support for multiple actions

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

Example setup:

sudo tc qdisc del dev eth0 root handle 1:0 prio
sudo tc qdisc add dev eth0 root handle 1:0 prio

sudo tc filter add dev eth0 pref 10 proto ip parent 1:0 \
rsvp session 10.0.0.1 ipproto icmp \
classid 1:1  \
action police rate 1kbit burst 90k pipe \
action ok

tc -s filter show dev eth0 parent 1:0

filter protocol ip pref 10 rsvp
filter protocol ip pref 10 rsvp fh 0x0001100a flowid 1:1 session
10.0.0.1 ipproto icmp
        action order 1:  police 0x5 rate 1Kbit burst 23440b mtu 2Kb
action pipe overhead 0b
ref 1 bind 1

        action order 2: gact action pass
         random type none pass val 0
