MAC addresses are at -ve offsets.
dst MAC starts at -14
src MAC at -8
ethertype at -2

Example:
#match my laptops MAC address ( 00:0b:97:97:4d:6a)
#for incoming packets on eth0 and count arp packets...
#
tc filter add dev eth0 parent ffff: protocol arp prio 10 u32 \
match u16 0x000B 0xffff at -14 \
match u32 0x97974D6A 0xffffffff at -12 \
match u16 0x0806 0xffff at -2 \
flowid 1:12 \
action ok

cheers,
jamal
