Subject: [BUG] ath9k_htc: new devices get name wlan%d if not in rules

I haven't narrowed it down to the exact build date where this breaks,
but I know that it works in compat-wireless-2011-05-01, and not in
compat-wireless-2011-05-11+ (including last night's build).  I had
trouble building compat-wireless-2011-05-04/05 so it was hard for me
to narrow it down.

However, if there is no udev rule already in
/etc/udev/rules.d/70-persistent-net.rules for the USB device's MAC
address (e.g., ATTR{address}=="4c:e6:76:12:ce:48") ... then the
interface comes up as wlan%d and does not get successfully renamed.
If it has an entry in 70-persistent-net.rules, then it will
successfully rename it.

In compat-wireless-2011-05-01 and earlier, if the device does not
exist in 70-persistent-net.rules, it gets a name and then it is added
to the rules file (e.g., as wlan0).

These are my results from an x86 Ubuntu 10.04 machine.
