From 67642ac2ac0b64f19089033115d1a8cbe326fd26 Mon Sep 17 00:00:00 2001 From: Tony Nguyen Date: Wed, 24 Jun 2020 09:04:22 -0700 Subject: [PATCH] iavf: Fix updating statistics [ Upstream commit 9358076642f14cec8c414850d5a909cafca3a9d6 ] Commit bac8486116b0 ("iavf: Refactor the watchdog state machine") inverted the logic for when to update statistics. Statistics should be updated when no other commands are pending, instead they were only requested when a command was processed. iavf_request_stats() would see a pending request and not request statistics to be updated. This caused statistics to never be updated; fix the logic.
