This patch should be applied after the ethdev change to avoid breaking
the build, I think?

You should be able to change the ethdev API, leaving the fail-safe
internals ignore the return value, then apply this patch and fix it.
This way the patchset should not break the build mid-series.

Otherwise good implementation with the rollback.
