That's already gone anyway in recent kernels anyway and the net: stuff
is broken currently.

When Greg fixes sysfs, the real way would be to follow the symlink
in /sys/class/net/ieee80211/ which links to (for
example) /sys/devices/pci0001:10/0001:10:12.0/ssb06:01/phy6, then go
back up one level and enumerate all net: objects in it.

Or, if you start from a netdev, you can see the phy80211 symlink.
