OK I can't come up with a better name and Jiri/Or convinced me this
should work ok so this works for me.

One question though going forward. We have devices with multiple
"switches" in them how does this work in a devlink environment? Do
we need some way to enumerate the switches and identify them. In
which case this attribute would be a global setting.

Thanks,
John
