As it turns out it can be read from /sys, but I do need it so I can

I'd actually prefer to *only* have the wiphy index, and I don't really
see a problem with moving the wiphy_idx from struct
cfg80211_registered_device to struct wiphy.
Ok, I'll try that. get_wiphy_idx can stay in place, not sure if I
should just drop it.
By having *only* the wiphy index you don't mean dropping the radio
names altogether? The don't seem useful but userspace may expect
them.
I find the name and addr more useful than an 'index', because if you
remove/add
a virtual phy, then the index will probably change, even if name and MAC
I don't think you can remove/add a phy without removing the hwsim
radio. A hwsim radio is tied to some wiphy at all times.
You can specify the MAC address and name (ie, wiphy0) when creating a hwsim radio.
You cannot specify the index. So, from a user-space perspective,
I think the name and MAC is more important than the index.
Anyway, I think you are correct to pay attention to the MAC address and use
that as the identifying key.
