The index cannot be used to reliably reconstruct a phy

But you still need to know the name to get at this to start with, so
what's the point?
cat /sys/class/ieee80211/<phyname>/name
<phyname>
or
cat /sys/devices/pci0000:00/0000:00:15.0/0000:03:00.0/ssb0:0/ieee80211/phy0/name
phy0
I use this to determine the phy device for a particular network device:
[root@dx-2u-ath5k lanforge]# cat /sys/class/net/wlan0/phy80211/name
wiphy0
Thanks,
Ben
