2010-01-20mac80211: move control.hw_key assignmentJohannes Berg4-49/+46
When mac80211 asks a driver to encrypt a frame, it must assign the control.hw_key pointer for it to know which key to use etc. Currently, mac80211 does this whenever it would software-encrypt a frame. Change the logic of this code to assign the hw_key pointer when selecting the key, and later check it when deciding whether to encrypt the frame or let it be encrypted by the hardware. This allows us to later simply skip the encryption function since it no longer modifies the TX control. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2010-01-20mac80211: remove useless setting of IEEE80211_TX_INTFL_DONT_ENCRYPTJohannes Berg1-3/+0
There's no value in setting a flag that will never be checked after this point, this seems to be legacy code -- I think previously the flag was used to check whether to encrypt the frame or not. Now, however, the flag need not be set, and setting it actually interferes if the frame will be processed again later. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2010-01-20mac80211: clear TX control on filtered framesJohannes Berg1-0/+8
When an skb survived a round-trip through the driver and needs to be re-used, its control information is definitely not valid any more, the driver will have overwritten it. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-01-20mac80211: move and rename misc tx handlerJohannes Berg1-12/+12

2010-01-20iwlwifi: remove extra statistics request from debugfsWey-Yi Guy1-41/+0
When reading current ucode statistics information from debugfs, in current implementation, it will always send a new "statistics request" to uCode. In normal operation, uCode should report the statistics per beacon interval. Remove this extra request to reduce the additional command exchanges between driver and uCode.

2010-01-20iwlwifi: software w/a for h/w bug cause Rx bit get clearWey-Yi Guy1-0/+10
This is a w/a for a hardware bug. the h/w bug may cause the Rx bit (bit 15 before shifting it to 31) to clear when using interrupt coalescing. This does not mean frames are lost - their processing is just delayed until next interrupt arrives.

2010-01-20iwlwifi: add num_of_sos_stats to statistics counterWey-Yi Guy2-2/+13
When uCode detects number of beacon missed consecutively above the internal missed beacon threshold (set by uCode), it will reset and re-tune the radio in order to get out of bad PHY state. This "num_of_sos_states" counter monitors number of time uCode encounters this bad condition and has to re-tune the radio.

2010-01-18p54pci: rx frame length checkChristian Lamparter1-0/+8
A long time ago, a user reported several crashes due to data corruptions which are likely the result of a not-100%-supported, or faulty? PCI bridge. ( http://patchwork.kernel.org/patch/53004/ ) This patch fixes entry #1. "1. p54p_check_rx_ring - skb_over_panic: Under a ping flood or just left running for a bit would panic with a skb_over_panic." As described in the mail: The invalid frame length causes skb_put to bailout and trigger a crash. Note: Simply dropping the frame is problematic, because if its content contains a tx feedback we would lose some portion of the device memory space.... And the driver/mac80211 should handle all other invalid data. Reported-by: Quintin Pitts <geek4linux@gmail.com> Signed-off-by: Christian Lamparter <chunkeey@googlemail.com> Signed-off-by: John W.

2010-01-18mac80211: fix sign error in pid controllerBob Copeland1-1/+1
While testing the pid rate controller in mac80211_hwsim, I noticed that once the controller reached 54 Mbit rates, it would fail to lower the rate when necessary. The debug log shows: 1945 186786 pf_sample 50 3534 3577 50 My interpretation is that the fixed point scaling of the target error value (pf) is incorrect: the error value of 50 compared to a target of 14 case should result in a scaling value of (14-50) = -36 * 256 or -9216, but instead it is (14 * 256)-50, or 3534. Correct this by doing fixed point scaling after subtraction.

Similar to 6000 and 1000 series, RTS/CTS is the recommended protection mechanism for 5000 series in HT mode based on the HW design. Using RTS/CTS will better protect the inner exchange from interference, especially in highly-congested environment, it also prevent uCode encounter TX FIFO underrun and other HT mode related performance issues.
