[RFC PATCH] hostapd: Add support for APuP

[Gio]

Hi!

Yeah it's me we have talked at WCW in Berlin ;-)

so about the 802.11ax capability, I guess I forgot to copy the non-6GHz 
capabilities, and this should fix it right?

#ifdef CONFIG_IEEE80211AX
+    copy_sta_he_capab( hapd, sta_ret,
+                       elems->he_capabilities, 
elems->he_capabilities_len );
     copy_sta_he_6ghz_capab(hapd, sta_ret, elems->he_6ghz_band_cap);
#endif // def CONFIG_IEEE80211AX


About the Block-Ack session, in the code I added nothing is done about 
that, if it is something that usually the station take initiative to do 
it I don't know well how to do that, but if something about that appears 
in the beacons like with capabilities and similar stuff it shouldn't be 
that hard to fix.

In my tests I could get high throughput about 200Mbit/s so I didn't 
notice this, I don't have the test setup ready now to reproduce, but I 
managed to find a picture (attached) I took of some iperf tests I made 
some time ago with a couple of AW7916-NPD WiFi 6e radios and APuP, it is 
curious that I could get such throughput without copy_sta_he_capab but 
just with copy_sta_he_6ghz_capab

Thanks for reviewing it ;)


Cheers

Gio
