Subject: [PATCH net 2/5] i40e: Fix firmware LLDP agent related warning
Date: Fri, 23 Jul 2021 10:10:20 -0700	[thread overview]
Message-ID: <20210723171023.296927-3-anthony.l.nguyen@intel.com> (raw)
In-Reply-To: <20210723171023.296927-1-anthony.l.nguyen@intel.com>

From: Arkadiusz Kubalewski <arkadiusz.kubalewski@intel.com>

Make warning meaningful for the user.

Previously the trace:
"Starting FW LLDP agent failed: error: I40E_ERR_ADMIN_QUEUE_ERROR, I40E_AQ_RC_EAGAIN"
was produced when user tried to start Firmware LLDP agent,
just after it was stopped with sequence:
ethtool --set-priv-flags <dev> disable-fw-lldp on
ethtool --set-priv-flags <dev> disable-fw-lldp off
(without any delay between the commands)
At that point the firmware is still processing stop command, the behavior
is expected.

Fixes: c1041d070437 ("i40e: Missing response checks in driver when starting/stopping FW LLDP")
