> There are some limitations on the some NICs (at least on ConnectX-6DX
> and BlueField2) with supporting FCS (frame checksum) scattering for
> the  tunnel decapsulated packets.
> 
> For the case only one of the features can be supported in the same time,
> and the new devarg "decap_en" is introduced to provide the choice to the
> users.
> 
> If FCS scattering feature is not supposed to be engaged by application,
> this new devarg should be specified as "decap_en=0", forcing the FCS
> feature enable and rejecting tunnel decap actions in the rte_flow engine.
> If FCS scatter is not needed and application supposes to use tunnel
> decapsulation in rte_flow, the devarg can be omitted or set to non-zero
> value (this is default settings).
