Ethernet frame structure

Ethernet frame structure

Ethernet frame structure

(OP)
Hello to all,

I'm interested in put, or create a new field with 10 bits on Ethernet type frame. For example, we have the Ethernet type frame were: http://en.wikipedia.org/wiki/Ethernet_frame and what I wont is to create a new Field with 10 bits length between the fields 802.1Q tag (optional) and Ethertype or length, ore maybe in other place of this frame.
I do not know if this requires a creation of a new Ethernet type, if exist a new ethernet frame that permit this (I think I have already read something about this, but Where I do not remember), or if this type of changes are possible in the actual 802.3 Ethernet frame structure.
Can someone give me some lights...
All advises and comments will be very appreciated.

Thanks in advanced,
Regards,
SLarry
