Subject: [for-next V2 11/11] net/mlx5: Separate ingress/egress namespaces for each vport
From: Gal Pressman <galp@...lanox.com>
Each vport has its own root flow table for the ACL flow tables and root
flow table is per namespace, therefore we should create a namespace for
each vport.
Fixes: efdc810ba39d ("net/mlx5: Flow steering, Add vport ACL support")
