A quick test on ingress

#tc qdisc add dev eth0 ingress

Classify all ip traffic

#tc filter add dev eth0 parent ffff: prio 1 protocol ip u32 match u32 0 
0 flowid :1

All arp

#tc filter add dev eth0 parent ffff: prio 2 protocol arp u32 match u32 0 
0 flowid :2

Anything else

#tc filter add dev eth0 parent ffff: prio 3 protocol all u32 match u32 0 
0 flowid :3

Look at the counters

#tc -s filter ls dev eth0 parent ffff:

Delete everything ingress on eth0

#tc qdisc del dev eth0 ingress


You can use ethertype protocol numbers in place of arp/ip.
Use the prio to make sure the catch alls are last in the filters you use 
- prio 1 is the highest for filters.
