> RX ptypes received from device control plane doesn't depend on vport info,
> but might vary based on the queue model. When the driver requests for
> ptypes, control plane fills both ptype_id_10 (used for splitq) and
> ptype_id_8 (used for singleq) fields of the virtchnl2_ptype response structure.
> This allows to call get_rx_ptypes once at the adapter level instead of each
> vport.
> 
> Parse and store the received ptypes of both splitq and singleq in a separate
> lookup table. Respective lookup table is used based on the queue model info.
> As part of the changes, pull the ptype protocol parsing code into a separate
> function.
