[dpdk-dev] [PATCH 04/11] net/mlx5: fix allow push VLAN without VID value

[Dekel Peled <dekelp@mellanox.com>]

Currently the push VLAN action requires a VID value, either from
existing VLAN item, or from following 'set VLAN vid' action.

This patch removes this limitation, allowing a push VLAN action with
vid value 0.
