Not a strong opinion, but maybe this should be part of David's patch?
i.e. for this patch we'll update "validated" version with 18.11.2,
and David will bump the "minimal supported" version in his patch along
with the actual changes to callback usage. This looks more consistent.
This will also allow us to not

Not a strong opinion, but maybe this should be part of David's patch?
i.e. for this patch we'll update "validated" version with 18.11.2,
and David will bump the "minimal supported" version in his patch along
with the actual changes to callback usage. This looks more consistent.
This will also allow us to not have strong 18.11.2 requirement (only
recommendation) for 2.11 branch where we'll not backport "enabled vhost
queues" patch-set.

What do you think?

[ovs-dev] [PATCH v1 1/1] dpdk: Use DPDK 18.11.2 release.

2019-06-20 Thread Ian Stokes 
Modify travis linux build script to use the latest DPDK stable release
18.11.2. Update docs for latest DPDK stable releases.

Note: due to commit [1] in DPDK 18.11.2, the behaviour of the vhost
destroy callback has changed. DPDK 18.11.2 is now the default DPDK
release currently supported. DPDK 18.11.1 and below are no longer
supported.

[1] 2b4e951cc341 ("vhost: fix passing destroyed device to destroy
callback")
