Currently, hns3 supports recognizing a lot of ptypes, but most
tunnel packet types are not reported to the API
rte_eth_dev_get_supported_ptypes.

And there are some errors in L2 and L3 packet recognition. The
ARP and LLDP are classified to L3 field in RX descriptor. So,
the ptype of LLDP and ARP packets will be set twice. And ptypes
are assigned by bitwise OR, which will eventually cause the ptype
result to be incorrect.

Besides, when a packet with only L2 header, its ptype will not
report by hns3 PMD. This is because the L2/L3 ptype table is not
initialized properly. In this case, the table query result is 0
by default.

As a result, it fixes missing supported ptypes and the mistake in

reporting its L2 type when the L3 type unrecognized..

net/mlx5: support concurrent access for hash list

In order to support hash list concurrent access, adding next:
1. List level read/write lock.
2. Entry reference counter.
3. Entry create/match/remove callback.
4. Remove insert/lookup/remove function which are not thread safe.
5. Add register/unregister function to support entry reuse.

For better performance, lookup function uses read lock to
allow concurrent lookup from different thread, all other hash list
modification functions uses write lock which blocks concurrent
modification and lookups from other thread.

The exact objects change will be applied in the next patches.
