[PATCH v3 00/15] hw/nvme: SR-IOV with Virtualization Enhancements

[Lukasz Maniak <lukasz.maniak@linux.intel.com>]

This is the version of the patch series that we consider ready for
staging. We do not intend to work on the v4 unless there are major
issues.

Changes since v2:
- The documentation mentions that SR-IOV support is still an
  experimental feature.
- The default value activates properly when sriov_max_v{i,q}_per_vf == 0.
- Secondary Controller List (CNS 15h) handles the CDW10.CNTID field.
- Virtual Function Number ("VFN") in Secondary Controller Entry is not
  cleared to zero as the controller goes offline.
- Removed no longer used helper pcie_sriov_vf_number_total.
- Reset other than Controller Reset is necessary to activate (or
  deactivate) flexible resources.
- The v{i,q}rfap fields in Primary Controller Capabilities store the
  currently active number of bound resources, not the number active
  after reset.
- Secondary controller cannot be set online unless the corresponding VF
  is enabled (sriov_numvfs set to at least the secondary controller's VF
  number)

The list of opens and known gaps remains the same as for v2:
