[dpdk-dev] [PATCH v1 4/4] ixgbe: Add support for scattered Rx with bulk allocation.

[Vlad Zolotarov <vladz@cloudius-systems.com>]

Simply initialze rx_pkt_burst callback to ixgbe_recv_pkts_lro_bulk_alloc() if
the conditions are right.

This is possible because work against HW in LRO and scattered cases is exactly the same
and LRO callback already supports the bulk allocation.
