Subject: [PATCH xfrm-next 23/26] net/mlx5e: Improve IPsec flow steering autogroup

From: Leon Romanovsky <leonro@...dia.com>

Flow steering API separates newly created rules based on their
match criteria. Right now, all IPsec tables are created with one
group and suffers from not-optimal FS performance.

Count number of different match criteria for relevant tables, and
set proper value at the table creation.
