infrastructure
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+In a virtualized environment, the programmer can enable a maximum of *64
Virtual Functions (VF)*
+globally per PCIE host-interface of the Intel Ethernet Switch FM10000 Series
device.
+Each VF can have a maximum of 16 queue pairs.
+The Physical Function in host could be only configured by the Linux* fm10k
driver
+(in the case of the Linux Kernel-based Virtual Machine [KVM]), DPDK PMD PF
driver doesn't support it yet.
+
+For example,
+
+* Using Linux* fm10k driver:
+
+ .. code-block:: console
+
+ rmmod fm10k (To remove the fm10k module)
+ insmod fm0k.ko max_vfs=2,2 (To enable two Virtual Functions per port)
+
+Virtual Function enumeration is performed in the following sequence by the
Linux* pci driver for a dual-port NIC.
+When you enable the four Virtual Functions with the above command, the four
enabled functions have a Function#
+represented by (Bus#, Device#, Function#) in sequence starting from 0 to 3.
+However:
+
+* Virtual Functions 0 and 2 belong to Physical Function 0
+
+* Virtual Functions 1 and 3 belong to Physical Function 1
+
+.. note::
+
+ The above is an important consideration to take into account when
targeting specific packets to a selected port.
