If the system has an Intel-based Ethernet network interface card that uses the i40e driver (for example the Oracle Quad 10 Gb or Dual 40 Gb Ethernet Adapter, or the Oracle Quad 10 Gb Ethernet Adapter), output notice messages are captured in syslog when the fwupdate command is run. This affects system running Oracle Solaris 11.3 SRU 21 and later. For example:
Mon May 29 12:45:02 PDT 2017 May 29 12:44:58 sca05-0a818b90 i40e: [ID 611667 kern.info] NOTICE: i40e0: i40e_nvmupd command status: 0 errno; 0 May 29 12:44:58 sca05-0a818b90 i40e: [ID 611667 kern.info] NOTICE: i40e0: i40e_nvmupd command status: 0 errno; 0 ... May 29 12:44:58 sca05-0a818b90 i40e: [ID 611667 kern.info] NOTICE: i40e0: i40e_nvmupd command status: 0 errno; 0 May 29 12:44:58 sca05-0a818b90 i40e: [ID 611667 kern.info] NOTICE: i40e0: i40e_nvmupd command status: 0 errno; 0
These messages are from the i40e driver and are benign. You can safely ignore these messages.
