Hi, I've recently installed a pair of 802.11n cards in my soekris net6501 and
alix in the hope that they'd some day be able to be used in hostap mode on
netbsd (no need for n, g would be quite sufficient) but alas that day seems not
to be quite here yet.

The cards are the mini-PCIe and mini-PCI versions of the Merlin (according the
athn man page) the former is an AR9280 and the latter latter an AR9220 (I
think, it's detected as an AR9280 by the athn driver, pcidevs doesn't seem to
know about the 9220)

The AR9280 works well in client mode, but I get huge packet loss when I try
to run it in hostap mode. My sporadic research seems to suggest that this is
due to missing support for powersaving in connected clients.

The AR9220 is not doing quite as well, it's detected, but the athn driver thinks
it's an AR9280 and also thinks it's only capable of 802.11a.
'ifconfig athn0 list scan' yields no results, but then there are no 802.11a
access points transmitting near that machine anyway so no wonder.

Now I have a couple of questions, is anyone working on the powersaving issue?
Is there much work involved? Is there something I can do?
