* mac80211: cleanup select_queueJohannes Berg2010-12-221-14/+6
| | | | | | | | | | There's a redundant rcu_read_lock/unlock pair, a redundant variable, and a few redundant accesses to the 1d_to_ac array. Fix this to make the code neater and easier to follow.

* ath9k: Reset keycache on resumeMohammed Shafi Shajakhan2010-12-223-1/+10
| | | | | | | | | | | | | | It looks like some hardware registers are left into undefined state after suspend/resume. At minimum, this can cause odd issues related to key cache and hardware trying to encrypt/decrypt frames unexpectedly. This seems to happen even when there is no keys configured, i.e., hardware can end up touching TX frames just based of invalid key cache context even if the driver is not asking a specific entry to be used. In addition, RX can likely be affected. This patch fixes this issue.

* rndis_wlan: scanning, workaround device returning incorrect bssid-list item ↵Jussi Kivilinna2010-12-221-18/+62
| | | | | | | | | | | | | | | | | | | count. Sometimes device returns wrong number of items in bssid-list. Appears that some specific beacons trigger this problem and leads to very poor scanning results. Workaround by ignoring num_items received from device and walkthrough full bssid-list buffer. v2: Fix buffer range checks and reading next item length. Old code read behind buffer on last item but didn't use those values as 'count' would also reach zero. Also fix resizing of buffer if device has larger buffer, old code assumed that BSSID-list OID would return same buffer size when it really can return yet another new larger length.

* ath5k: Track current TX power separately from max TX powerBruno Randolf2010-12-222-4/+4
| | | | | | | | | | | | | | | | | | Add a new variable to keep track of the currently configured tx power. Before max_pwr was re-used for keeping the maximum allowed power as well as the current configuration. Doing a min() on it allows you to lower the txpower, but how would you be able to make it higher again? This patch fixes that by adding a new variable ah_cur_pwr which is used instead of txp_max_pwr to keep the current configuration. txp_max_pwr is used to check if we are within the limits. Another problem fixed by this patch is that it avoids setting a zero txpower when things are initialized first and the current power is not yet set.

* ath9k: fix aphy / wiphy idle mismatchLuis R. Rodriguez2010-12-222-0/+2
| | | | | | | | | | | | | | | | | | ath9k supports its own set of virtual wiphys, and it uses the mac80211 idle notifications to know when a device needs to be idle or not. We recently changed ath9k to force idle on driver stop() and on resume but forgot to take into account ath9k's own virtual wiphy idle states. These are used internally by ath9k to check if the device's radio should be powered down on each idle call. Without this change its possible that the device could have been forced off but the virtual wiphy idle was left on.

* ath9k_hw: fix PA predistortion HT40 maskFelix Fietkau2010-12-203-9/+13
| | | | | | | | | | | | | | | | | | | | The commit 'ath9k_hw: Disable PAPRD for rates with low Tx power' changed the code that sets the PAPRD rate masks to use only either the HT20 mask or the HT40 mask. This is wrong, as the hardware can still use HT20 rates even when configured for HT40, and the operating channel mode does not affect PAPRD operation. The register for the HT40 rate mask is applied as a mask on top of the other registers to selectively disable PAPRD for specific rates on HT40 packets only. This patch changes the code back to the old behavior which matches the intended use of these registers. While with current cards this should not make any practical difference (according to Atheros, the HT20 and HT40 mask should always be equal), it is more correct that way, and maybe the HT40 mask will be used for some rare corner cases in the future.

| | | | | | | | | | | | | | To improve aggregation length, there should not be more than two fully formed A-MPDU frames in the hardware queue. To ensure this, the code checks the tx queue length before forming new A-MPDUs. This can reduce the throughput (or maybe even starve out A-MPDU traffic) when too many non-aggregated frames are in the queue. Fix this by keeping track of pending A-MPDU frames (even when they're sent out as single frames), but exclude rate control probing frames to improve performance.

| | | | | | | | | | | | | | | | | | | The Mesh Control header only includes 0, 1 or 2 addresses. If there is one address, it should be interpreted as Address 4. If there are 2, they are interpreted as Addresses 5 and 6 (Address 4 being the 4th address in the 802.11 header). The address extension used to hold up to 3 addresses instead of the current 2. I'm not sure which draft version changed this, but it is very unlikely that it will change again given the state of the approval process of this draft. See section 7.1.3.6.3 in current draft (8.0). Also, note that the extra address that I'm removing was not being used, so this change has no effect on over-the-air frame formats. But I thought I better remove it before someone does start using it. Signed-off-by: Javier Cardona <javier@cozybit.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
