Subject: [net-next 7/8] net/mlx5: Add eswitch ACL vlan trunk api
From: Ariel Levkovich <lariel@...lanox.com>
The patch is adding an api to add/remove vlan id
to/from the eswitch ACL tables, per vport.
With this api, the driver can add and remove vlan ids
to the vport's ACL table and control the vlan ids the
vport can receive and transmit.
By default, the eswitch configuration allows the vport
to receive and transmit all of the vlan ids.
Once the first vlan id is added to the ACL table using
this api for a specific direction (ingress/egress),
the rest of the vlan ids are blocked in that direction
and will have to be added to the table as well if required
by the vport.
