Dear Openvswitch Maintainers,

We are scoping the src:dpdk 19.11 -> 20.11 transition. If possible,
we'd really like to go to bullseye with the latest upstream LTS, as
19.11 is EOL at the end of next year.

OVS support for DPDK 20.11 will be released upstream in v2.15, which is
due for release on February 15 [1].
Bullseye transition freeze is on January 12 [2], so the dates
don't align very well.

So we are looking to formulate a plan that you can agree with, to sort
this out.

Based on experience, what Ubuntu usually does to meet release deadlines
is to upload from git earlier than the release, so that all major
incompatibilities can be sorted. And then after the freeze, once the
release is officially out, do a final upgrade to the released version -
since a similar enough version was uploaded from git, and at the end of
a release cycle it's mostly bug fixes that land upstream, such an
upload is acceptable.

So we'd like to propose the following ideas:

- between now and December: upload v2.14, to minimize the later jump
- by the first week of January: upload 2.15~git from the tip of the
master branch to experimental
- stabilize and sort eventual build issues
- upload dpdk 20.11 and ovs 2.15~git to unstable
- upload 2.15 proper in February as a bug fix upload to unstable

What do you think? Does this sound like a workable plan?

We are of course happy to help - Ubuntu will go through the exact same
process for 21.04, so a lot of the work is "shared".

Thank you!

Kind regards,
Luca Boccassi
