Current vector RX can't always set the packet_type properly.
To be more specific:
a) it never sets RTE_PTYPE_L2_ETHER
b) it doesn't handle tunnel ipv4/ipv6 case correctly.
c) it doesn't check is IXGBE_RXDADV_PKTTYPE_ETQF set or not.
While a) is pretty easy to fix, b) and c) are not that straightforward
in terms of SIMD ops (specially b).
So far I wasn't able to make vRX support packet_type properly without
noticeable performance loss.
So for now, just remove that functionality from vector RX and
update dev_supported_ptypes_get().
