[ovs-dev] [PATCH 0/4] OVN: RFC for Logical/Physical Separation for localnet and SW gateway

[Darrell Ball]

This patch series updates the OVN SB schema to support logical/physical
separation for localnet and SW gateway. A SB physical endpoint table is
introduced to achieve this, which will also support various other encaps 
besides single vlan.

The existing tag field for localnet is left for now, for comparison.  

Very little testing has been done.

Existing OVN test support is not updated and hence the localnet test fails; later
the existing localnet test will be updated to use sbctl for physical endpt binding. 

Once L2 support is in place for the new SW gateway using ovn-controller to
program flows, a corresponding SW gateway test will be added similar to the ovs-vtep
test.

This patch does not support the hardware gateway yet which requires vlan bindings
updates to the physical port table of the vtep DB. This would be done by 
ovn-controller-vtep by reading the SB DB. 

This patch also mentions deprecation of some vtep options - vtep-logical-switch
and vtep-physical-switch, but this is not supported by this patch and may be 
demonstrated in a further patch. The motivation to do this is to remove physical
context from the NB DB. The new SB physical endpoint table facilitates this 
objective, hence the comments.  

Darrel  Ball (4):
  Update OVN SB to use physical endpoints table
  Update OVN SB documentation to use physical endpoints table and
    mention possible deprecation of vtep logical port options which
    would require other changes for HW VTEP side and cleanup of OVN NB
    schema
  Update sbctl to support OVN SB physical endpoint table usage and
    associated changes in the port binding table
  Update flow generation for localnet and future software gateway to
    source physical endpoint encapsulation from the OVN SB physical
    endpoint table
