DPDK community has several emails discussion on this topic,
these mails name is "FW: Issues with ixgbe and rte_flow",
items like VLAN can already have several valid "types"
(0x88a8, 0x8100, 0x9100), and who knows what will come up
in the future.And ixgbe_flow just ignores the types when do
filter configuration. So it may be reasonable to delete the
related tpid check process.
Also add some more comment log on stack explanation.
Fixes: 11777435c72 ("net/ixgbe: parse flow director filter")
