Nack
Above code has no impact, it has been added to drivers to highlight this
feature to driver maintainers.
This feature is added to ethdev layer and requires driver support, but
driver maintainer may miss that this feature exists at all. With above
change driver maintainer can chose to remove that line meaning they are
aware but not prefer to support this feature or properly add support it.
For your case, no need to add it explicitly, if driver doesn't support
RTE_ETH_DEV_CAPA_FLOW_RULE_KEEP, no action is needed.
