Traffic shapping filtering on the Ethenet Type number

Hi ALL,


I'm trying to use 'tc' filter to classify packets based on the
EthernetNumber (http://www.iana.org/assignments/ethernet-numbers) and
not on the Protocol Number
(http://www.iana.org/assignments/protocol-numbers).

Since I'm using my own Ether Number from the experimental range, I know
I can't use the iptable MARK target feature as 'iptables' only works on
the IP header level.

So, I'm trying to use the u32 filter option of 'tc' but with no result,
is it possible to classify packets on the ethernet level?

Can anyone give me some pointers or a tc filter exemple to mach the
ethernet number on a packet?

Thanks

I spent a some more time fishing in google and I came across this issue
in a FAQ from lartc.org

Looks like the trick is using u32 filter but with NEGATIVE offsets!
I would never though of that!
