Hi, after switching to kernel 3.8.8 (ubuntu quantal to raring), I'm
unable to change my alfa AWUS036NH mac address; a simple:
ifconfig <device> down
ifconfig <device> hw ether <random hw>
results in:
SIOCSIFHWADDR: Invalid argument
I tried the drivers shipped with the distribution,
compat-drivers-3.9-rc4-2-su and compat-drivers-2013-03-28-4-u aswell;
all to no avail.
Any help appreciated, I'm able to recompile/test if needed.
Thank you for your time.

Hi, I have an ath9k-driven integrated card active at the same time (wlan0);
but only one wlan interface (wlan1) active on the rt2800usb phy, running in
managed mode.
Thank you for your time.

Do you have multiple wifi interfaces or just that single one?

Hi!
I have the same problem with RT5370 (rt2800usb driver).
compat-drivers-v3.7.9-1 still works, so this must be a regression in
kernels after 3.8...

Basically the driver got more picky and only allows the last 3 bit of
the MAC address changed. I just found out that if you generate your new
MAC accordingly it works!
I wonder wether this is addr_mask is necessary for all RT chipsets,
since mine (RT5372) happily accepted different MAC addresses before,
also in multi-AP configurations...

After digging a bit into linux-stable.git I found the culprit: this
regression comes from commit #
6c50f9459e62eb133563fd23606f68bfc9d120e8 (rt2x00: Use addr_mask to
disallow invalid MAC addresses in mutli-bssid mode) ; reverting it
fixes the problem, tested by me in compat-drivers-2013-03-28-5-u .
I can't tell if reverting that commit adds any trouble as I'm not a
developer; however I'm sure you guys will know how to handle the
situation.
