[dpdk-dev] [PATCH v2] fm10k: set packet type for multi-segment packets

[Michael Frasca <michael.frasca@oracle.com>]

When building a chain of mbufs for a multi-segment packet, the
packet_type field resides at the end of the chain. It should be
copied forward to the head of the list.

Also, uses RTE_LIBRTE_FM10K_RX_OLFLAGS_ENABLE to guard packet-type
computation. The mbuf fields are not copied when this define is not set.

Fixes: fe65e1e1ce61 ("fm10k: add vector scatter Rx")

v2:
- Only copy hash, ol_flags, and packet_type to 'start' when 
  RTE_LIBRTE_FM10K_RX_OLFLAGS_ENABLE is defined.
