Although the Open Flow specification specified support for 802.1AD (qinq)
as well as push and pop vlan headers, So far Open vSwitch has only
supported a single tag header. This patch implements 802.1AD in the kernel
module.
This patch accompanies version 14 of the user level openvswitch patch
submitted to openvswitch dev list.
V14: Add outer tpid to flow_key
V13: Fix incorrect encoding and decoding of netlink to/from key
attributes.
V12: Fix some problems and issues pointed out by reviewers. When parsing
netlink attributes Ether types other then 0x88a8 as outer tpid.
V11: Add inner tpid to flow key. Fix separate inner encap attribute
when parsing netlink attributes. Merge 2 patches to consolidate
qinq changes.
V10: Implement reviewer comments: Consolidate vlan parsing functions.
Splits netlink parsing and flow conversion into a separate patch. Uses
double encap attribute encapsulation for 802.1ad. Netlink attributes
now look like this:
eth_type(0x88a8),vlan(vid=100),encap(eth_type(0x8100), vlan(vid=200),
encap(eth_type(0x0800), ...))
The double encap atributes in this version of the patch is incompatible with
old versions of the user level 802.1ad patch. A new user level patch which
is also being submitted simultaneously to openvswitch dev mailing list.
V9: Includes changes suggested by reviewers
V8: Includes changes suggested by reviewers
V7: Includes changes suggested by reviewers
V6: Rebased to net-next
V5: Use encapsulated attributes

patch and the user code patch see the OVS dev mailing list,
