Subject: Re: [PATCH] ethdev: add template table resize API
Date: Mon, 29 Jan 2024 17:08:50 +0200 (IST)	[thread overview]

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
