>
> This new API supersedes all the legacy filter types described in rte_eth_ctrl.h.
> It is slightly higher level and as a result relies more on PMDs to process and
> validate flow rules.
>
> Benefits:
>
> - A unified API is easier to program for, applications do not have to be
> written for a specific filter type which may or may not be supported by
> the underlying device.
>
> - The behavior of a flow rule is the same regardless of the underlying
> device, applications do not need to be aware of hardware quirks.
>
> - Extensible by design, API/ABI breakage should rarely occur if at all.
>
> - Documentation is self-standing, no need to look up elsewhere.
>
> Existing filter types will be deprecated and removed in the near future.

Hi Adrien,
ETHERTYPE in ether header is 2 bytes, so I think "uint16_t type" is more appropriate here, what do you think?
Thanks,
