How am I supported to verify that these packet types are really
recognized by the driver? The patch should include the part
of Rx burst callback which does recognition and fill in
corresponding data in mbuf.

You can verify the PTYPE via sending & receiving certain packets.
After setting the cmd verbose, the corresponding PTYPE may show
up in the testpmd. You can then check if the PTYPE is exactly what
you just sent.
The ptype_tbl will be filled when func idpf_get_pkt_type is called.
And then the corresponding part will be filled in Rx burst phase.
This part patch will also be improved to make it more clear. Thanks!
