‐ If more than 8 functions are required the server must support ARI ‐ see
Alternative Routing ‐ ID Interpretation (ARI) on page 328 .
‐ Solarflare also recommend setting
pci=realloc
in the kernel
configuration grub file ‐ refer to Kernel Configuration on page 328 for
details.
5 To identify which physical port a given network interface is using:
# cat /sys/class/net/eth<N>/device/physical_port
6 If the Solarflare driver is loaded, PFs will also be visible using the
ifconfig
command where each PF is listed with a unique MAC address.
