Title:
Simplify l2pop driver code
Status in neutron:
Expired
Bug description:
Simplify l2pop driver code.
l2pop driver unable to properly decide about port add/remove notifications
when it gets called with different port status from nova and l2 agents through
different workers during instance migrations.
There were many suggestions to modify the port status in plugin(some
suggested to change it to BUILD, some reviewers to DOWN, etc ..) during
migration(see the comments in https://review.openstack.org/#/c/215467/ ), so
that l2pop can properly decide about port's binding host based on status.
Deciding about which status to set to port in plugin and using the same in
l2pop driver is confusing, and reviewers giving different opinion(comments in
https://review.openstack.org/#/c/215467/ ).
Kevin suggested that l2pop shouldn't depend on port status for
deciding about host. Instead it should use binding info in db, which
reviewers of the patch( https://review.openstack.org/#/c/215467/)
agreed.
note: There was a separate bug

fail to create flood flows with multiple workers"
