Yes for dst mac A1:B2:C3:D4:E5:F6 it''s

tc filter add dev eth0 parent 1:0 protocol ip prio 1 \
u32 match u16 0x0800 0xFFFF at -2 \
match u32 0xC3D4E5F6 0xFFFFFFFF at -12 \
match u16 0xA1B2 0xFFFF at -14 \
flowid 1:1

For src I assume you can just change the offsets - I''ve not tried it as
there is an iptables match for src MAC.

Hi Grace,

I guess the best(most flexible) way is to use iptables(netfilter) to
mark the packets and then use tc filter to match the marks.

"Traffic-Control-HOWTO" should answer most of your questions.
