2010-04-09iwlwifi: clean up last_phy_resJohannes Berg
The last_phy_res[100] variable is used in an odd way. The first byte of it is used as a flag, and the rest as the data. Thus, the array need only be 61 bytes, since it is just the flag and a struct iwl_rx_phy_res (which is 60 bytes). Clean this up by splitting the variable into two: last_phy_res and last_phy_res_valid, using correct types for both (struct and bool). While doing all this also move the variables to the _agn part of the hw-specific union since they only apply to A-MPDUs.

2010-04-09iwlwifi: remove wrong key use checkJohannes Berg
Default WEP keys and regular keys are not allocated from the same space in the firmware, so we shouldn't use the same bits to indicate in use. For default WEP keys, however, mac80211 won't allow using the same key index twice, so the check is not necessary at all -- add/remove are perfectly nested due to those checks. Other keys are allocated in the device in a global array that only has a certain number of slots, so for that we need to keep the allocation bitmap; but the 802.11 key index isn't relevant there.

2010-04-09iwlwifi: make WEP key restoring explicitJohannes Berg
The firmware clears default WEP keys on transitions to !associated, so we need to restore them just like stations. This is rather implicit as part of sending a station right now, which is odd. Make it explicit instead and only for agn since 3945 doesn't use hw crypto for WEP. Due to that, iwl_send_static_wepkey_cmd is now only used in iwl-sta.c and can be static.

2010-04-08ath5k: fix race condition in tx desc processingBob Copeland
As pointed out by Benoit Papillault, there is a potential race condition between the host and the hardware in reading the next link in the transmit descriptor list: cpu0 hw tx for buf completed raise tx_ok interrupt process buf buf->ds_link = 0 read buf->ds_link This change checks txdp before processing a descriptor (if there are any subsequent descriptors) to see if hardware moved on.

2010-04-08ath5k: clean up queue manipulationBob Copeland
Review spotted a couple of strange invocations to ieee80211_wake_queues that could potentially cause problems: - queues are awakened in the calibration tasklet before phy calibration, and then again after calibration - queues are awakened inside reset when we're trying to drain the ath5k transmit queues, and again after reset is completed (in callers to ath5k_reset_wake). In both cases the first wake is unnecessary, so remove it. Signed-off-by: Bob Copeland <me@bobcopeland.com> Acked-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W.

2010-04-08ath5k: correct channel setting for 2.5 mhz spacingBob Copeland
These channels aren't selectable anyway, but our calculations for 2.5 mhz frequencies are incorrect. The value is supposed to be: (frequency - reference) * (10/25) i.e., divide by 2.5, but we were instead doing: (10 * frequency - reference) / 25. Additionally, the check for (frequency % 5 == 2) had an extra subtraction that wasn't in madwifi HAL.

2010-04-07ath5k: Adaptive Noise Immunity (ANI) ImplementationBruno Randolf
This is an Adaptive Noise Imunity (ANI) implementation for ath5k. I have looked at both ath9k and HAL sources (they are nearly the same), and even though i have implemented some things differently, the basic algorithm is practically the same, for now. I hope that this can serve as a clean start to improve the algorithm later. This also adds a possibility to manually control ANI settings, right now only thru a debugfs file: * set lowest sensitivity (=highest noise immunity): echo sens-low > /sys/kernel/debug/ath5k/phy0/ani * set highest sensitivity (=lowest noise immunity): echo sens-high > /sys/kernel/debug/ath5k/phy0/ani * automatically control immunity (default): echo ani-on > /sys/kernel/debug/ath5k/phy0/ani * to see the parameters in use and watch them change: cat /sys/kernel/debug/ath5k/phy0/ani Manually setting sensitivity will turn the automatic control off. You can also control each of the five immunity parameters (noise immunity, spur immunity, firstep, ofdm weak signal detection, cck weak signal detection) manually thru the debugfs file. This is tested on AR5414 and nearly doubles the thruput in a noisy 2GHz band. Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-04-06ath9k: remove ah->mask_reg, it's never used properlyPavel Roskin
ah->mask_reg was used to hold different data throughout the driver. ath9k_hw_init_interrupt_masks() used it to save the value written to AR_IMR. ath9k_hw_set_interrupts() used it to hold the interrupt mask as defined in enum ath9k_int. Those masks differ in many bits. Use ah->imask instead of ah->mask_reg in ath9k_hw_set_interrupts() and ath9k_hw_updatetxtriglevel(). That's what the code was meant to do. ah->imask is initialized in ath9k_start(), so we don't need to initialize it from ah->mask_reg. Once it's done, ah->mask_reg becomes write-only, so it's replaced with a local variable in ath9k_hw_init_interrupt_masks().
