Hi list,

I write a dessector for 802.1QinQ packets,whose ethertype field values
is 0x9100 (default). I hope it will be added in the next version.

This attachments are source files.

Some Requirement:
http://www.ethereal.com/lists/ethereal-users/200605/msg00142.html

* The IEEE 802.1Q-in-Q VLAN Tag is purpose to expand the VLAN space
* by tagging the tagged packets,thus producing a "double-tagged" frame.
* The expanded VLAN space allows the service provider to provide certain
* services,such as Internet access on specific VLANs for specific
customers,
* and yet still allows the service provider to provide other types of
* services for their other customers on other VLANs.


Thanks.
DuBingyao

0x9100 isn't default, it's just an _example_ value since it's not
registered at IANA. Therefore we cannot create a dissector like this for
it.

Why creating a new dissector for it? Why not extend the 802.1Q dissector?

Good idea.

0x9100 is default in the realization of the most important verdors ,such as
cisco.

And,what should we do in this situation:

You could add a preference to the 802.1Q dissector to accept another
number besides default 8100. That 'another number' would be
initialized to 9100 then.
