Despite the product name, I'm pretty sure this isn't a MIMO device. It
appears just to be a normal ZD1211B and we have never heard of these
devices having more than 1 RF. I guess they named this product this way
to make it appear that it fits in with the rest of their XtremeMIMO
product range.

As pointed out by Daniel Drake, the zd1211rw driver used several
different rate values and names throughout the driver. He has
written a patch to change it and tweaked it after some pretty wild
ideas from my side. But the discussion helped me to understand the
problem better and I think I have nailed it down with this patch.
A zd-rate will consist from now on of a four-bit "pure" rate value
and a modulation type flag as used in the ZD1211 control set used
for packet transmission. This is consistent with the usage in the
zd_rates table. If possible these zd-rates should be used in the
code.

While in monitor mode the zd1211rw received only a limited
set of packets. This patch forwards now all packets the device
receives. Notify that while monitoring no FCS checks are done; so
strange packets might appear in the network sniffer of your
choice.
ATTENTION: Support for multiple interfaces on a single ZD1211
device is currently broken. So this code works only on the first
interface.
Here is an example to put the device in monitor mode.
iwconfig wlan0 mode monitor
ifconfig wlan0 up
iwconfig wlan0 channel 10

While playing with the firmware a while back, I discovered a way to
access the device's entire address space before the firmware has been
loaded.
Previously we were loading the firmware early on (during probe) so that
we could read the MAC address from the EEPROM and register a netdevice.
Now that we can read the EEPROM without having firmware, we can defer
firmware loading until later while still reading the MAC address early
on.
This has the advantage that zd1211rw can now be built into the kernel --
previously if this was the case, zd1211rw would be loaded before the
filesystem is available and firmware loading would fail.
Firmware load and other device initialization operations now happen the
first time the interface is brought up.
Some architectural changes were needed: handling of the is_zd1211b flag
was moved into the zd_usb structure, MAC address handling was obviously
changed, and a preinit_hw stage was added (the order is now: init,
preinit_hw, init_hw).

Zen Kato's device has a regulatory domain value of 0x49, which is not an
IEEE 802.11 code and is not even identified in the vendor driver.
Recent versions of the vendor driver don't even look at the regdomain
value any more, and just allow channels 1-11 everywhere. This patch
brings us more in line with that behaviour, by allowing channels 1-11
for regdomains which we don't know about.

The vendor driver code suggests that CR47 patching happens on every channel
change for every RF (depending on bit 8 in POD).
Due to a bug in their driver (upper bits of RF_Mode get zeroed out, then
are examined for 1s when setting some other flags), this isn't actually
what happens, and their generic CCK patching routine never takes effect.
Some of their RF configurations do include explicit (duplicated) code
for CR47 patching though. This patch makes zd1211rw match that
behaviour.

This patch adds support for another radio appearing in new devices: the
Ubec UW2453. It's more complicated than the other RF's we support, but
Ubec publish full tech specs so we're able to understand the vendor code
relatively well.
Now that we support UW2453, we also support Atheros' new USB chip: the
AR5007UG. From the little info we have, this appears to be just a
rebranded ZD1211B.
This RF code doesn't work very well -- lots more TX/RX errors than the
other RFs. However, the vendor driver doesn't do any better, so this is
all we can do for now.
