net/mlx5: support modifying VLAN priority on VLAN header
This commit adds support for modifying the VLAN priority (PCP) field in about-to-be-pushed VLAN header. This feature can only modify the PCP field of a new VLAN header yet to be pushed. It does not support modifying an existing or already pushed VLAN headers. Signed-off-by: Moti Haimovsky <motih@mellanox.com> Acked-by: Viacheslav Ovsiienko <viacheslavo@mellanox.com>
