Verify the `i40evf` Driver (Oracle Solaris)

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

Note - The Oracle Solaris 11.3 SRU8 OS is the first release to support this adapter. You can upgrade to or install this release, but the version of the driver must be the same on both the client and the server.

Check the version of the installed 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.

Manually load the driver.
```
# modload /kernel/drv/arch/i40evf
```
If the i40evf is not installed, do so now.
```
# add_drv -i '"pciex8086,154c" "pciex8086,1571"' i40evf
```
Note - If the i40evf driver is not listed, the driver might not be loaded. You can use the modload(1M) command to load the driver if needed.
```
# modload /kernel/drv/arch/i40evf
```
where arch is amd64 for 64-bit Intel servers or sparcv9 for Oracle SPARC servers.
