I submitted a RFC series[1] to add support for SR-IOV emulation to virtio-net-pci. During the development of the series, I fixed some trivial bugs and made improvements that I think are independently useful. This series extracts those fixes and improvements from the RFC series.

(Michael S. Tsirkin) - Noted the impact on the guest of patch "pcie_sriov: Do not reset NumVFs after unregistering VFs". (Michael S. Tsirkin) - Changed to use pcie_sriov_num_vfs(). - Restored pci_set_power() and changed it to call pci_set_enabled() only for PFs with an expalanation. (Michael S. Tsirkin) - Reordered patches. - Link to v4: https://lore.kernel.org/r/20240214-reuse-v4-0-89ad093a0...@daynix.com Changes in v4: - Reverted the change to pci_rom_bar_explicitly_enabled(). (Michael S.
