Template table resize API allows to add new flows immediately after
rte_flow_template_table_resize completed.
A multi-threaded application can add new and update old flows simultaneously.
A single resize-and-update API would require to lock PMD for entire operation.
For application with 1e6 flows doubling a table would end up with
considerable down time.
The rte_flow_template_table_resize_complete was added for PMDs that cannot
differentiate flows created before and after table resize.
Regards,
Gregory
