GENERAL
=======
- OVS 2.10
-- Branch created Wednesday 25th
-- Release targeted for 13th August
-- Feature freeze in place
-- Bug fixes only accepted for 2.10

- Discussion about path towards using newer DPDK
-- Newer DPDK will be needed for some new features being developed
-- (e.g. full hw offload)
-- OVS will need changes for newer DPDK API
-- Thomas expressed concern that jumping several DPDK releases will mean
a lot of OVS change at once
-- Requested a branch for working with latest DPDK be provided to ease
integration and reduce duplicate work
-- Questions about if it would be later merged with master, how
maintained etc.
