| Subject: i40e: Fix firmware LLDP agent related warning |
| |
| From: Arkadiusz Kubalewski <arkadiusz.kubalewski@intel.com> |
| |
| [ Upstream commit 71d6fdba4b2d82fdd883fec31dee77fbcf59773a ] |
| |
| 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") |
