Hi Jouni, Luis, Margit, Andreas,

I can control advertised basic_rates parameter in hostap
(via iwpriv) and acx111 (in code, iwpriv is TODO).
I don't know how to control basic_rates for prism54.

Now, I am trying to assoc acx111 STA to prism54 AP.

In acx111, it is possible to have 1, 2, 5.5, 11 and 22Mbit/s
rates in basic_rates set, but not other rates.
I've coded all five of them to be included.

acx111 can associate with prism54 when prism54
is iwconfig'ed to 24M auto, but not with
one iwconfig'ed to 54M auto.

hostap in monitor mode sees these beacons for 24M auto:

tcpdump: WARNING: ifh: no IPv4 address assigned
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on ifh, link-type IEEE802_11 (802.11), capture size 65535 bytes
23:07:20.689111 Beacon (ear2) [1.0* 2.0* 5.5* 11.0* 6.0* 9.0* 12.0* 18.0* 1.5 Mbit] ESS CH: 1
23:07:20.791510 Beacon (ear2) [1.0* 2.0* 5.5* 11.0* 6.0* 9.0* 12.0* 18.0* 1.5 Mbit] ESS CH: 1

and this for 54M auto:

tcpdump: WARNING: ifh: no IPv4 address assigned
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on ifh, link-type IEEE802_11 (802.11), capture size 65535 bytes
23:07:48.545322 Beacon (ear2) [1.0* 2.0* 5.5* 11.0* 6.0* 9.0* 12.0* 18.0* 1.5 0.5 0.5 54.0* Mbit] ESS CH: 1
23:07:48.647711 Beacon (ear2) [1.0* 2.0* 5.5* 11.0* 6.0* 9.0* 12.0* 18.0* 1.5 0.5 0.5 54.0* Mbit] ESS CH: 1

(tcpdump must be a bit broken with regard to 802.11 beacons.
0.5M rate does not exist :) )

I shall post a bug in prism54 bugzilla.... ok, here:
