Subject: [PATCH net-next 15/18] net/mlx5: E-Switch, Introduce HCA cap and E-Switch vport context
From: Saeed Mahameed <saeedm@...lanox.com>
E-Switch vport context is unlike NIC vport context, managed by the
E-Switch manager or vport_group_manager and not by the NIC(VF) driver.
The E-Switch manager can access (read/modify) any of its vports
E-Switch context.
Currently E-Switch vport context includes only clietnt and server
vlan insertion and striping data (for later support of VST mode).
