    * Tech-board selected David's approach
    * Automated checks will be in CI after David's patch

  * Some PMD patches may be postponed to -rc2

* next-net-crypto
  * Pull request sent
  * There is a performance concern on some ipsec-gw patches,
    they can go in -rc2 if the issue is solved
  * CPU crypto from last release may be breaking ABI, need to confirm
    and discussed dummy variable is missing, may be postponed to next release
  * Some PMD changes are postponed to -rc2

* next-net-eventdev
  * Pull request sent, it is a small set

* next-net-virtio
  * All commit pulled to next-net
  * virtio vDPA drive will be postponed to next release
  * Some patches waiting user change and some are under review
  * Can be some more patches for -rc2

* next-net-intel
  * Nothing critical, most of the patches have been pulled
  * 'fm10k' patches are not reviewed, may go in -rc2 if reviewed
    otherwise will be postponed to next release

* LTS

  * 17.11.10-rc1 released, please test and report results
    * https://mails.dpdk.org/archives/dev/2020-January/154915.html
    * Release planned on January / February

  * 18.11.6-rc2 released, please test and report results

    * Intel will plan a validation, it won't be full validation
    * Release planned on 31st January


OvS
---

* Using DPDK experimental APIs discussed, it is accepted to use once as
  exception, so feature won't be blocked
  * DPDK need to figure out how to backport removing experimental tags to the
    LTS releases



DPDK Release Status Meetings

Thanks Ferruh for confirmation.
For cryptodev we don't have such inline functions, plus the we add
new entry at the bottom of struct rte_cryptodev_ops, so I believe we
are safe here.
