Subject: net/qede: allow firmware to query LAN stats
X-Git-Tag: spdx-start~6558
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=8a9c69ae4a481256c16812269ecfd1e813323991;p=dpdk.git

net/qede: allow firmware to query LAN stats

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

Fixes: ec94dbc57362 ("qede: add base driver")
