[dpdk-dev] [PATCH 2/2] qede: return LAN stats to MFW

[Rasesh Mody]

From: Harish Patil <harish.pa...@qlogic.com>

Under certain scenarios, MFW periodically polls the driver
for LAN statistics. This patch implements the osal hook to
fill in the stats.

Fixes: ffa002d318d36 ("qede: add base driver")
