The PF is responsible for allocating its VFs. This is handled by the PF driver. Testing this ability requires reloading the relevant driver telling it how many VFs to allocate. The Intel 82576 driver is called <code>igb</code>. The Neterion X3100 driver is called <code>vxge</code>. Each of those drivers take module parameters which will tell the driver how many VFs to allocate when loaded. Such as: | The PF is responsible for allocating its VFs.
