But it's still used as a key, no? Just the value changed. If you treat
it as a key then you'd just have it for a frame incoming and outgoing?

So you're saying you have code that broke? How did it break though, I

Well, it was always rather awkward since it was the *second* address :)

You can query the ID/index already through the netlink API, or even
from sysfs since the virtual device name is essentially
