Subject: [PATCH net-next 3/4] net/mlx4: Prepare VLAN macros for 802.1ad Hardware accelerated support

From: Hadar Hen Zion <hadarh@...lanox.com>

To add Hardware accelerated support in 802.1ad vlan, replace
Current VLAN macros to CVLAN.
Replace:
MLX4_WQE_CTRL_INS_VLAN
MLX4_CQE_VLAN_PRESENT_MASK
With:
MLX4_WQE_CTRL_INS_CVLAN
MLX4_CQE_CVLAN_PRESENT_MASK
