1) is easily solvable, just drop the ifindex style attributes and always
force the user to enter the bus and bus-topology id.

But why? Use can easily get that info and map it to devlink index. It
aligns with nl80211 iface.

Do you really want to do commands like:
myhost:~$ dl dev show pci_0000:01:00.0
?

Yes, exactly I would. I would put them into a boot-up script based on my
system configuration and can be sure it will work the next boot, too, and
adapt them when I replace the hardware or do some configuration changes.

I think sysadmins or scripts are the primary users of this interface not
kernel developers which switch their settings around all the time, no?

I can easily add this to the userspace tool to accept "pci_0000:01:00.0"
format and to map it internally to devlink index. No problem.
