> Subject: [dpdk-dev] [PATCH V2 0/5] table: add key mask for hash tables
> Main changes:
> 1. The key_mask parameter is added to all the hash tables that were
>    previously missing it, as well to the hash compute function. This was
>    first started in DPDK 2.0, but was only implemented for a couple of
>    hash tables. The benefit of this approach is that it allows for better
>    performance for large keys (bigger than 16 bytes), while it preserves
>    the same performance for small keys [Q&A1].
> 2. The precomputed key signature (i.e. non-"do-sig") versions have been
>    removed for all the hash tables, so now the key signature is always
>    computed on every lookup. Note that this approach also allows for the
>    precomputed key signature scheme [Q&A2].
> 3. API cleanup: single parameter structure common for all hash tables.
> Q&A:

Applied on next-pipeline tree.
