[dpdk-dev] [PATCH] ixgbe: fix check for split packets

[Bruce Richardson]

The check for split packets to be reassembled in the vector ixgbe PMD
was incorrectly only checking the first 16 elements of the array instead
of all 32. This is fixed by changing the uint32_t values to be uint64_t
instead.

Fixes: cf4b4708a88a ("ixgbe: improve slow-path perf with vector scattered Rx")
