Re: Any reason AID is not in the NL80211_STA_INFO enumeration?

To sniff /AX stations, it is helpful to know their AID.  So, any problems
with adding it to 'iw station dump' output?

No, no problem at all. I guess it was just never added because it
originally comes from userspace (hostapd), and so didn't really need to
be sent back. But yeah, we have trivial infrastructure to send it back,
so sure, why not.

Ok, thanks for the response.

 From looking at debugfs for a station device, there is the netdev AID:

cat /debug/ieee80211/wiphy0/netdev\:wlan0/aid
1

And there is a peer AID:

cat /debug/ieee80211/wiphy0/netdev\:wlan0/stations/04\:f0\:21\:c2\:fd\:b0/aid
0

For sniffing AX, I'd need to use '1' here as far as I can tell.  Maybe for station
devices the peer is always zero?  And for AP devices, the peer IDs are what is useful
and the netdev AID is not?


Thanks,
Ben
