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 disable-fw-lldp on ethtool --set-priv-flags disable-fw-lldp off (without any delay between the commands) At that point the firmware is still processing stop command, the behavior is expected.
