Hrm - poking inside there and this seems to be one of those
classifiers that hasnt been getting a lot of love. Doesnt
support actions well for example.
It seems to work for me:
----------
/sbin/tc -V
tc utility, iproute2-ss140610
uname -a
Linux jhs-1 3.16.0-rc2+ #4 SMP Fri Aug 29 11:13:53 EDT 2014 x86_64

sudo /sbin/tc qdisc add dev eth0 root handle 1:0 prio
sudo /sbin/tc filter add dev eth0 pref 10 proto ip parent 1:0 rsvp
session 10.0.0.1 ipproto icmp classid 1:1 police rate 1kbit burst 90k

/sbin/tc -s filter show dev eth0 parent 1:0

Now lets send a fast ping:
sudo ping -f 10.0.0.1 -c 10000
.......

/sbin/tc -s filter show dev eth0 parent 1:0
