rtlwifi: rtl8723be: Fix array dimension problems
Commit
a619d1abe20c leads to the following static checker warning:
drivers/net/wireless/rtlwifi/rtl8723be/phy.c:667 _rtl8723be_store_tx_power_by_rate()
error: buffer overflow 'rtlphy->tx_power_by_rate_offset[band]' 4 <= 5
This warning arises because the code is testing the indices for the wrong maximum
values. In addition, the tests merely putput a warning, and then procedes to
corrupt memory. With this change, any such invalid memory access is avoided.

Date: Wed Feb 20 11:33:00 2013 +0200
iwlwifi: disable 8K A-MSDU by default
Supporting 8K A-MSDU means that we need to allocate order 1
pages for every Rx packet. Even when there is no traffic.
This adds stress on the memory manager. The handling of
compound pages is also less trivial for the memory manager
and not using them will make the allocation code run faster
although I didn't really measure.
Eric also pointed out that having huge buffers with little
data in them is not very nice towards the TCP stack since
the truesize of the skb is huge. This doesn't allow TCP
to have a big Rx window.
See https://patchwork.kernel.org/patch/
2167711/ for details.
Note that very few vendors will actually send A-MSDU.
Disable this feature by default.

The commit
80b4205b "ath9k: Fix OFDM weak signal detection for AP mode"
prevented weak signal detection changes from taking effect in AP mode on
all chipsets, claiming it is "not allowed".
The main reason for not disabling weak signal detection in AP mode is
that typically beacon RSSI is used to track whether it is needed to
boost range, and this is unavailable in AP mode for obvious reasons.
The problem with not disabling weak signal detection is that older
chipsets are very sensitive to high PHY error counts. When faced with
heavy noise, this can lead to an excessive amount of "Failed to stop

mwl8k: Adding support to gather survey per channel
Survey stats such as channel busy time, rx busy time
and noise are collected when sw_scan starts for every
switched new channel. This happens till sw_scan stops.
All the collected stats are shared up when get_survey()
is called.
This implements support for ACS feature from Hostapd.

ieee80211: remove function ieee80211_{dsss_chan_to_freq, freq_to_dsss_chan}
Function ieee80211_{dsss_chan_to_freq, freq_to_dsss_chan} have been
replaced with ieee80211_{channel_to_frequency, frequency_to_channel}.
There should be no users of the two functions now. So remove them.
