[dpdk-dev] [PATCH v2 3/3] net/mlx5: add tos and ttl validation on E-Switch

This patch adds the type-of-service and time-to-live IP header
fields validation on E-Switch, both for match pattern and
VXLAN encapsulation action IP header itesm. The E-Switch flows
will use the common mlx5_flow_validate_item_ipv4/6 routines
with added extra parameter, specifying the supported fields
mask.
