Subject: [net-next 13/16] net/mlx5: E-Switch, Use vport metadata matching by default

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

Multiple features use metadata matching such as bond vport
in live migration, multi-port RoCE mode, stacked devices;
hence, enable vport metadata matching by default.

Fixes: 1e62e222db2e ("net/mlx5: E-Switch, Use vport metadata matching only when mandatory")
