For the AVM stick you need the one-stage firmware (opposite to the "old" two-stage one) from
http://www.kernel.org/pub/linux/kernel/people/mcgrof/firmware/ar9170/ar9170.fw
as stated on the ar9170 driver's webpage (http://linuxwireless.org/en/users/Drivers/ar9170).
Check the md5sum after downloading.
I don't think it will ever be included into the kernel, rather into some Linux distribution package.

BTW, questions about the ar9170 driver are more likely to be answered on the linux-wireless mailing list, this one
is the list for the original driver made by Atheros.

HTH,
Joerg.
