Hi,
we are trying to integrate a RTL8192CU based WiFi adapter (TP-Link TL-WL822N)
on a PowerPC based platform running a vendor-supplied/modified 3.12 kernel

Hi,

Hi,
we are looking for well supported USB WiFi chips/modules with the following
requirements
* Be able to support AP mode
* Support at least 20 concurrent clients (stations)
* Support multiple SSIDs
* (preferred, optional: Support 2x2 802.11gn)
We did a survey through the various wiki

FFT max index retrieval was not retrieved correctly for HT20/HT40 FFT
frames. Fixing the retrieval allows us to remove the fixup function as
well. While at it, split the spectral_max_index function into versions
for ht20 and ht40 to simplify the code.
