> Subject: [PATCH v6 04/18] net/mlx5: add modify field hws support
> 
> This patch introduces support for modify_field rte_flow actions in HWS
> mode. Support includes:
> 
> - Ingress and egress domains,
> 	- SET and ADD operations,
> 	- usage of arbitrary bit offsets and widths for packet and metadata
> 	fields.
> 
> 	Support is implemented in two phases:
> 
> 	1. On flow table creation the hardware commands are generated, based
> 	on rte_flow action templates, and stored alongside action template.
> 	2. On flow rule creation/queueing the hardware commands are updated
> with
> 	values provided by the user. Any masks over immediate values, provided
> 	in action templates, are applied to these values before enqueueing
> rules
> 	for creation.
