Subject: [PATCH mlx5-next 02/18] net/mlx5: E-Switch, Rename egress config to
 generic name

From: Vu Pham <vuhuong@...lanox.com>

Refactor vport egress config in offloads mode

Refactoring vport egress configuration in offloads mode that
includes egress prio tag configuration.
This makes code symmetric to ingress configuration.
