That will shape all traffic leaving eth0 as it is.

If you mean that you don't want to shape arp or other traffic aswell as 
ip then you will need to add PRIO as root so you can use filters and add 
tbf to one of the PRIO classes.

TBF tends to tweak the parameters you pass to it so it's best to check 
what you got after adding it and modify your settings. eg with the above 
I see -

tc -s -d qdisc ls dev eth0
qdisc tbf 8007: rate 500000bit burst 5Kb/8 mpu 0b peakrate 1000Kbit mtu 
1539b/8 mpu 0b lat 39.2ms
...

note the latency.
