2010-05-07ath9k_common: drop incomming frames with an invalid hardware rateLuis R. Rodriguez1-2/+1
ath9k_common (used by ath9k and ath9k_htc) trusts the frames blessed by hardware as OK are infact correct even if the rate seen by the driver is unrecognized. ath9k_common just treats these frames in mac80211 as frames as frames under 1 mbps rate. It seems this might not be the best thing to do as other parts of the frame might not be valid so just drop these frames for now. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-05-07ath9k_common: move the rate status setting into ath9k_process_rate()Luis R. Rodriguez1-13/+27
This has no real functional change, this just moves the setting the the mac80211 rate index into ath9k_process_rate(). This allows us to eventually make ath9k_process_rate() return a negative value in case we have detected a specific case rate situation which should have been ignored. Signed-off-by: Luis R.

2010-05-07ath9k_htc: Fix beaconing in IBSS modeSujith4-45/+13
The current way of managing beaconing in ad-hoc mode has a subtle race - the beacon obtained from mac80211 is freed in the SWBA handler rather than the TX completion routine. But transmission of beacons goes through the normal SKB queue maintained in hif_usb, leading to a situation where __skb_dequeue() in the TX completion handler goes kaput. Fix this by simply getting a beacon from mac80211 for every SWBA and free it in its completion routine. Signed-off-by: Sujith <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-05-07ath9k: fix another source of corrupt framesFelix Fietkau1-2/+8
Atheros hardware supports receiving frames that span multiple descriptors and buffers. In this case, the rx status of every descriptor except for the last one is invalid and may contain random data. Because the driver does not support this, it needs to drop such frames. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-05-07ar9170usb: remove deprecated aggregation codeChristian Lamparter2-598/+12
This patch removes the incomplete AMPDU implementation in ar9170usb. The code in question is: * too big and complex (more than 550 SLOC.) This is enough to qualify for a new separate code file! * unbalanced quantity & quality over-engineered areas like: * xmit scheduling and queuing frames for multiple HT peers * redundant frame sorting are confronted by gaping holes: * accurate transmission feedback * firmware error-handling and device reset * HT rate control algorithm * error-prone Since its inclusion, hardly anything was done to fix any of the outlined flaws from the initial commit message. => This also indicates poor maintainability. * relies heavily on several spinlocks. As a result of this shortcomings, the code is slow and does not even support the most basic 11n requirement: HT station mode. Therefore, I request to purge my heap of **** from the kernel: "ar9170: implement transmit aggregation". The next item on the agenda is: (re-)start from scratch with an adequate design to accommodate the special requirements and features of the available frameworks and tools.

2010-04-27ath9k: Avoid corrupt frames being forwarded to mac80211.Vivek Natarajan2-5/+5
If bit 29 is set, MAC H/W can attempt to decrypt the received aggregate with WEP or TKIP, eventhough the received frame may be a CRC failed corrupted frame. If this bit is set, H/W obeys key type in keycache. If it is not set and if the key type in keycache is neither open nor AES, H/W forces key type to be open. But bit 29 should be set to 1 for AsyncFIFO feature to encrypt/decrypt the aggregate with WEP or TKIP.

2010-04-27ath9k_hw: Fix TX interrupt mitigation settingsLuis R. Rodriguez1-4/+6
TX interrupt mitigation reduces the number of interrupts by addressing several interrupt actions (AR_IMR_TXOK, AR_IMR_TXDESC) all in one interrupt so when enabling it discard setting the other interrupts. Without this TX interrupt mitigation would actually increase the number of interrupts two-fold. We still leave TX interrupt mitigation disabled as it is still being tested. Signed-off-by: Luis R.
