I think, the series is not addressed all the v3 comments. I think, the
missing ones are
1) Use dynamic logging
2) Split the patches based on eventdev ops:
example:
See the example from latest dpaa eventdev driver:
http://dpdk.org/dev/patchwork/project/dpdk/list/?submitter=Sunil
3) Fix check-patch and check-git-log.sh errors.
Wrong headline format:
doc:update 18.02 release notes
Wrong headline prefix:
eventdev/opdl: opdl eventdev pmd unit test function
event/*: apply the three new capability flags for
sw/dppa2/octeontx
Wrong headline lowercase:
event/opdl: add the opdl pmd main body and helper function
eventdev/opdl: opdl eventdev pmd unit test function
event/*: apply the three new capability flags for
sw/dppa2/octeontx
maintainers: add the opdl pmd maintainer information
doc: add eventdev opdl pmd docuement
Headline too long:
event/*: apply the three new capability flags for
sw/dppa2/octeontx
