  From: Chengwen Feng <fengchengwen@huawei.com>

Currently, the packet type calculated by
vlan/ovlan/l3id/l4id/ol3id/ol4id fields have the following problems:
1) Identify error when exist vlan strip which will lead to the data
buffer has non vlan header but mbuf's ptype have L2_ETHER_VLAN flag.
2) Some packet identifies error, eg: hardware report it's RARP or
unknown packet, but ptype will marked with L2_ETHER .

So driver will calculate packet type only by l3id/l4id/ol3id/ol4id
fields.

Fixes: 0e98d5e6d9c3 ("net/hns3: fix packet type report in Rx")
Fixes: bba636698316 ("net/hns3: support Rx/Tx and related operations")
