CC'ing those who worked on that driver.

Please try today's release, last night's release was broken due to
zd1211rw-mac80211 --> zd1211rw move, among other things. Let me know
how it goes and what kernel you are using.

wmaster0 is an internal master device used only by mac80211. It serves
as a holder for all interfaces we have, and represent the underlying
hardware. For example, when TXing your wlan0 STA interface will
actually add IEEE-802.11 header data to a frame with just Ethernet
headers, and then pass it down to the master device for actual
transmission using the low level drivers. Anyway, your wlan0 is an
interface, in your case a STA interface, this is the real guy you
would be configuring. The idea with is to be able to support multiple
interfaces at the same time using the same wireless card (say an AP
and a STA).

No, if we could we would hide that from users, I believe there may be
patch coming for that soon.

Using compat-wireless-2.6 I get my wmaster0 as 'eth3' actually and I
think that's making network manager angry (my wlan0 is actually
wlan0_rename too).

I believe what Will was trying to tell you is that:

ADDRCONF(NETDEV_UP): wlan0: link is not ready

indicates to us that your wireless interface was not yet associated.

Best thing to do is to try to get you to use the latest driver, we'll
be able to help a lot better that way. You can try wireless-2.6.git
tree yourself or we can try to get the compat-wireless-2.6 package
working for you.

Well lets find out, I believe it should be supported and working with
the current drivers.
