2015-05-11ath10k: increase relay buffer size of spectral scanPeter Oh1-1/+4
Spectral scan supported by ath10k has capability to monitor and report through whole bands and channels, but current buffer size is too small to save reported spectral scan data. This results in dropping 5G channel reports at all when dual band card is used, so that users are not able to analyze spectral environments. Hence increase the buffer size to fix the problem. A spectral data size is vary based on the number of bins, so the unit buffer size, 1140, is chose to minimize relay buffer fragmentation. The total buffer size is also chose in tradeoff with spectral scan support vs. kernel memory consumption. Since theoretical maximum buffer size, 9.5MB, can be consumed with 512 bins in dual bands, we target to cover up to 128 bins for all channels in dual bands and due to the buffer size limitation, spectral scan with bin number bigger than 128 needs to be run on single band each.

Since we can identify the FFT frames on the report by checking the consistency of their magnitude info, we can process all of them, even when some of them are corrupted. This patch introduces two functions to quickly verify the integrity of the mag_info fields and some further tweaks to detect the frames in the report and process them. Note that in case of missing bytes we don't duplicate them, instead we leave them as zeroes. This way we get less noise on the FFT plot.

2015-05-09ath9k: Fix hanlding of maximum magnitude indexNick Kossifidis2-10/+28
Maximum magnitude index is a 5bit signed integer, convert to an 8bit signed integer and then "shift" it so that it can be used as an array index. Note that the current implementation adds +1 to the index value (so it can't be used as an array index) and it's only valid for HT20 channels. Note that the maximum magnitude index is not being used by the userspace tools that parse FFT samples (they just use maximum magnitude) so this doesn't break userspace compatibility.
