[openstack-dev] [Neutron][L2 Agent][Debt] Bootstrapping an L2 agent debt repayment task force

I had done some work on looking at L2 agents and identifying how we may
want to go about creating a Modular L2 Agent framework to make the agent
code more modular, avoid code replication across multiple L2 agents, and to
make adding new features and writing new agents (if/when necessary) easier.
I will be happy to take a stab at writing the blueprint/spec based on that
work and what is specified in the etherpad [1].

I had to take a few weeks off from work and therefore had to miss the
Summit; This happened right around the time that "paying our technical
debts" was becoming a common phrase in Neutron (for good reasons) and from
what I can gather from the etherpad [1] the scope for this effort may have
expanded and there are others who have volunteered to work on various
aspects of this effort. So, if there are others who want to start the "task
force" by writing this blueprint/spec, that is perfectly fine with me. If
not, I will be happy to get that started.

Subject:	[openstack-dev] [Neutron][L2 Agent][Debt] Bootstrapping an L2
            agent debt repayment task force

At the recent summit, we held a session about debt repayment in the
Neutron agents [1].  Some work was identified for the L2 agent.  We
had a discussion in the Neutron meeting today about bootstrapping that

The first order of business will be to generate a blueprint
specification for the work similar, in purpose, to the one that is
under discussion for the L3 agent [3].  I personally am at or over
capacity for BP writing this cycle.  We need a volunteer to take this
on coordinating with others who have been identified on the etherpad
for L2 agent work (you know who you are) and other volunteers who have
yet to be identified.

This "task force" will use the weekly Neutron meeting, the ML, and IRC
to coordinate efforts.  But first, we need to bootstrap the task
force.  If you plan to participate, please reply to this email and
describe how you will contribute, especially if you are willing to be
the lead author of a BP.  I will reconcile this with the etherpad to
see where gaps have been left.

I am planning to contribute as a core reviewer of blueprints and code
submissions only.
