[0/2] net/mlx5: scatter FCS with decapsulation

  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).

Suanming Mou (2):
  common/mlx5: add scatter FCS with decap capability query
  net/mlx5: add decap enable device argument

Series rebased and applied to next-net-mlx,
