[dpdk-dev] [PATCH v2 4/5] net/qede: fix stats flow as per new 100Gb queue allocation method

[Shahed Shaikh <shshaikh@marvell.com>]

As per new method, need to consider hw stats of queues from
both engines. This patch fixes the stats collection flow accordingly.

Fixes: 2af14ca79c0a ("net/qede: support 100G")
