> 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.
