output, for all PFs and VFs on given device:

pci/0000:af:00:
name rss size 8 unit entry size_min 0 size_max 24 size_gran 1
resources:
name lut_512 size 0 unit entry size_min 0 size_max 16 size_gran 1
name lut_2048 size 8 unit entry size_min 0 size_max 8 size_gran 1

What is contributing to the hardness, this is not just one for all ice
PFs, but one per device, which we distinguish via pci BDF.

How?

code is in ice_adapter_index()

If you pass 2 pfs of the same device to a VM with random BDF, you get 2
ice_adapters, correct?

Right now, yes

What I want is to keep two ice_adapters for two actual devices (SDNs)
