The i40e and i40evf software package comes bundled in the Oracle Solaris software. Two device drivers are available for this adapter:
i40e - Physical function (PF) driver
i40evf - Virtual function (VF) driver
# strings /kernel/drv/$(isainfo -n)/ i40evf | grep i40evf ... i40evf 1.0.12
If the version number is not at least 1.0.12, you must install the latest driver, or you can reinstall the OS.
See Hardware and Software Requirements for more information.
# modload /kernel/drv/arch/i40evf
If the i40evf is not installed, do so now.
# add_drv -i '"pciex8086,154c" "pciex8086,1571"' i40evf
# modload /kernel/drv/arch/i40evf
where arch is amd64 for 64-bit Intel servers or sparcv9 for Oracle SPARC servers.
