net/mlx5: support match on GTP flags
This patch adds to MLX5 PMD the support of matching on
GTP header item v_pt_rsv_flags.
This item is contained in 1 byte of the format:
-------------------------------------------
| bit | 0 - 2 | 3 | 4 | 5 | 6 | 7 |
|-----------------------------------------|
| value | Version | PT | Res | E | S | PN |
-------------------------------------------
Matching is supported only for GTP flags E, S, PN.
Therefore values 0 to 7 are supported.
Mask must be set accordingly:
... gtp v_pt_rsv_flags is 1 v_pt_rsv_flags mask 0x07 ...
