Bug Description

Currently not all PCI function properties are passed through to the guest. Instead, some default assumptions are being made, which can make it difficult or impossible to properly handle the PCI function in the guest. The correct approach is to pass the host PCI device's properties down to the guest, except for properties that are overridden by the user.

Feature request for the kernel part.
Target - kernel >=5.9, therefore backport

Changing to Incomplete until code got released upstream (and potential backport was made available, in case cherry-pick is not possible).
Please notice that this can be very tight in time for groovy since you mentioned that the code will land in "kernel >= 5.9".

Ok, so since we have 5.10 in hirsute:
linux-generic | 5.10.0.14.16 | hirsute
I'll update this ticket to Fix Released.
