VFs for this port in the Number of VFs Per PF control window.
The 2x1G+2x10G 57800 allows up to 64 VFs per 10G port (the
57800's two 1G ports do not support SR-IOV). The 2x10G 57810
allows up to 64 VFs per port. The 4x10G 57840 allows up to 32 VFs
per port.

Configuration menu (which appears only if NPAR mode is selected in
the Virtualization Mode control). In the NIC Partitioning Configuration
page, select each Partition “N” Configuration menu and set the
Number of VFs per PF control. The total number of VFs assigned per
PF on a single physical port cannot exceed the numbers assigned in
Step f.

64 in increments of 8 (default is 16).
If Multi-Function Mode is set to NPAR, display the Main Menu

Function to configure and enter the appropriate value in the
Number of VFs per PF box.
