tc filter protocol is ethertype most examples use ip you can use a 
number or all, arp etc. You need a different prio for each type.

You can also match protocol at -2 with u32/u16.
You do the same for macs with mac of target machine 00:C1:26:0F:04:AD.

tc filter add dev eth0 protocol ip parent 12: prio 1 u32 \
match u16 0x00c1 0xffff at -14 \
match u32 0x260f04ad 0xffffffff at -12 \
flowid X:Y

User priority - you'll need to tcpdump -eXX and work out what offsets work.
