15.1.1. Endpoint Testbench for SR-IOV

The Endpoint testbench for SR-IOV supports up to two PFs and 32 VFs per PF.
First, the testbench configures the link and accesses then Configuration Space. Then, the testbench performs the following tests:
  1. A single memory write followed by a single memory read to each PF and VF.
  2. For PF0 only, the testbench drives memory writes to each VF and followed by memory reads of all VFs.
