>
> Bring more flexibility and control over both flow rule insertion
> and packet matching mechanisms. Introduce 2 new flow table types:
>
> 1. Allow a user to specify the insertion type used in template tables.
> The insertion type is responsible for choosing the appropriate key
> value used to map inserted flow rules into a template table.
>
> Flow rules can be inserted by calculating the hash value for
> the pattern or inserted by index via the new create_by_index() API.
> The idea of the index-based insertion is to avoid additional matches
> and simply execute predefined actions after jumping to the index.
>
> The insertion into an already occupied index results in an error.
> The old rule must be destroyed first. An index cannot be bigger than
> the size of the table, otherwise, the rule is rejected as well.
>
> 2. Allow a user to specify the hash calculation function used in template
> tables. The hash calculation type is responsible for the calculation of
> the flow rule index a packet would hit upon arrival at the table.
>
> Control over this is useful for applications with custom RSS algorithms,
> for example. An application can select various packet fields to serve as
> a hash calculation source and jump to the appropriate flow rule location.
> The RSS hash result will be used as the index in the table. For the linear
> hash function, the mapping is one-to-one and the hash result is the index.
> For other hash functions, the index is the hash result module table size.
> The RSS hash result can be retrieved via modify_field API: HASH_RESULT.

> RFC:
> https://patchwork.dpdk.org/project/dpdk/patch/20221214022110.393410-1-
> akozyrev@nvidia.com/
> v2: changed the behavior in case of insertion into the same index.
