00044f17af carl9170: export HW random number generator
All AR9170 hardware have a 16-Bit random number generator.
The documentation claims the values are suitable for
"security keys".

The "throughput" is around 320Kibit/s. It's slow, but it
does work without introducing any special offload
firmware commands.

e338a85e21 ath9k: Fix invalid noisefloor reading due to channel update
While switching b/w HT20/40, the current channel's nf values
are updated into history buffer. Since the current channel's
channel type, channel flag got updated before reading
nf value from hw. This channel type mismatch is causing invalid
readings when hw is on ht20 but getnf tries to read on extn chains.

Before doing hw reset the current channel's noisefloor readings
are updated into history buffer. The extension chain's readings

While moving from HT40 to HT20, the extn chain's readings are
skipped though the current channel is in ht40. This patch updates
extn chain reading based on channel flag.

a63d7e67fc mwl8k: Traffic to clients gets affected when one client leaves a cyrpto bss
When a client disassociates from a crypto enabled bss, data traffic to
other clients connected to the bss is stalled. This was due to a boolean
variable used to keep track if HW crypto is enabled i.e. if set key has
been called to add a key.  This flag was being reset every time delete
key was called e.g when a station leaves the bss. Once the flag is
reset, rx status flags were not being set for connected clients which
disrupts traffic to these clients. Fix this issue by not resetting the
flag since we do not need to reset this flag during the life time of the
bss.

f3d4505de5 ath9k: remove eeprom txgain override for minor version < 19
ath9k_hw_4k_get_eeprom() overrides the eeprom value for txgain if the
minor version is not 19 or above with a value of 0.
ar9002_hw_init_mode_gain_regs() relies on this information to
determine whether this is a high power wifi card or not. The override
caused the driver to always use the 'normal' power tables even for
high power devices if their minor version was not high enough. Thus
leading to reduced power output.

This isn't needed for the AR9285; the check originated with the
AR9280 setup code which requires the EEPROM version check.
