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.

Changes in v8:
- Clarified that "hw/pci: Replace -1 with UINT32_MAX for romsize" is
not a bug fix. (Markus Armbruster)
- Squashed patch "vfio: Avoid inspecting option QDict for rombar" into
"hw/pci: Determine if rombar is explicitly enabled".
(Markus Armbruster)
- Noted the minor semantics change for patch "hw/pci: Determine if
rombar is explicitly enabled". (Markus Armbruster)
- Link to v7: https://lore.kernel.org/r/20240224-reuse-v7-0-29c14bcb952e@daynix.com
Changes in v7:
- Replaced -1 with UINT32_MAX when expressing uint32_t.
(Markus Armbruster)
- Added patch "hw/pci: Replace -1 with UINT32_MAX for romsize".
- Link to v6: https://lore.kernel.org/r/20240220-reuse-v6-0-2e42a28b0cf2@daynix.com
Changes in v6:

- Removed a reference to PCI_SRIOV_CTRL_VFE in hw/nvme.
(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-v4-0-89ad093a07f4@daynix.com
Changes in v4:
- Reverted the change to pci_rom_bar_explicitly_enabled().
(Michael S. Tsirkin)
- Added patch "pcie_sriov: Do not reset NumVFs after unregistering VFs".
