net/mlx5: fs, add match on ranges API
Range is a new flow destination type which allows matching on
a range of values instead of matching on a specific value.
Range flow destination has the following fields:
- hit_ft: flow table to forward the traffic in case of hit
- miss_ft: flow table to forward the traffic in case of miss
- field: which packet characteristic to match on
- min: minimal value for the selected field
- max: maximal value for the selected field
Note:
- In order to match, the value in the packet should meet
the following criteria: min <= value < max
- Currently, the only supported field type is L2 packet length
