What I'm 'aiming' for is that this is a common problem;
I.e., having multiple PCI functions per a physical port is a constellation
which exists in several devices.

I think the community strives in such scenarios to uphold a unite front
for user experience - if the 'right' answer is that the network device
associated with the first PCI function is the configuration node in such
cases, then we should strive making it so for all drivers.

You can't refrain from user assigning the first partition to a VM.
In such a case, you receive quite a bizarre configuration when you
all a ~random device on some VM to control the physical port.
