Beilei Xing e536c2e328 net/i40e: fix parsing QinQ packets type 
Previously, PTYPE filed in the RX descriptors is not set properly
for QinQ packets. The wrong PTYPE is generated because outer Tag did
not have ORT/PIT configured, so fix this issue by configuring ORT/PIT.
This patch also changes bitmask of outer VLAN tag in L2 header
to support RSS and flow director for QinQ.

Fixes: 4861cde461 ("i40e: new poll mode driver")
Fixes: 4072d503aa ("i40e: fix VLAN bitmasks for input set")
