  proto_hdr defines a bit mask of the protocol sequence as RTE_PTYPE_*,
The last RTE_PTYPE* in the mask indicates the split position.

To get the split position from proto_hdr, the order of judgement should
be from inner to outer layer, so for tunneling packets the tunnel header
should be placed at the end of the judgement condition.

Fixes: 629dad3ef325 ("net/ice: support buffer split in scalar Rx")
