[dpdk-dev] [PATCH v3 3/4] event/dlb2: fix extraction of HW scheduling type

[David Marchand]

From: Timothy McDaniel <timothy.mcdaniel at intel.com>

The HW scheduling type was not being extracted properly
in the vector optimizaed dequeue path. It was also not
being recorded in the xstats.

Fixes: 000a7b8e7582 ("event/dlb2: optimize dequeue operation")
