=======
GENERAL
=======

- Ian will take over collecting the DPDK patches into a pull request (Ben)

- DPDK userspace conf (Kevin)
-- Gave summary of LTS and API/ABI stability discussions at DPDK userspace
-- Some discussion about having OVS LTS use DPDK LTS - seems like good idea
-- Likely to be a yearly DPDK LTS
-- The rate of new features in DPDK means that there are breaks in
API/ABI. Nothing to indicate that this will change over the short term.
-- Thomas would like to see more participation in helping review to get
new API's right
-- John McN sent summary of discussions here

HARDWARE OFFLOAD
================

future

to add more actions.
