Hi list,
I extend the 802.1Q dessector for resolving 802.1QinQ packets,whose ethertype field values is 0x9100 (default in the realization of the most important verdors).
I hope it will be added in the next version.
This attachments are patches files.
Some Requirement:
* 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.
