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.

2011-08-24ath9k: Fix invalid noisefloor reading due to channel updateRajkumar Manoharan1-3/+14
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. Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: John W.

2011-08-24ath9k: Fix noisefloor history update for extn chainsRajkumar Manoharan1-2/+1
Before doing hw reset the current channel's noisefloor readings are updated into history buffer. The extension chain's readings are considered only if the current channel was configured in HT40. 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.

2011-08-22mwl8k: Traffic to clients gets affected when one client leaves a cyrpto bssNishant Sarmukadam1-3/+0
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. Signed-off-by: Nishant Sarmukadam <nishants@marvell.com> Signed-off-by: John W.
