2013-06-12wl12xx/wl18xx: scan all 5ghz channelsEliad Peller
Due to a typo, the current code copies only sizeof(cmd->channels_2) bytes, which is smaller than the correct sizeof(cmd->channels_5) size, resulting in a partial scan (some channels are skipped).

2013-04-16mac80211: support secondary channel offset in CSAJohannes Berg
Add support for the secondary channel offset IE in channel switch announcements. This is necessary for proper handling of CSA on HT access points. For this to work it is also necessary to convert everything here to use chandef structs instead of just channels. The driver updates aren't really correct though. In particular, the TI wl18xx driver update can't possibly be right since it just ignores the new channel width for lack of firmware API. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2013-02-15mac80211: stop toggling IEEE80211_HT_CAP_SUP_WIDTH_20_40Johannes Berg
For VHT, many more bandwidth changes are possible. As a first step, stop toggling the IEEE80211_HT_CAP_SUP_WIDTH_20_40 flag in the HT capabilities and instead introduce a bandwidth field indicating the currently usable bandwidth to transmit to the station. Of course, make all drivers use it. To achieve this, make ieee80211_ht_cap_ie_to_sta_ht_cap() get the station as an argument, rather than the new capabilities, so it can set up the new bandwidth field. If the station is a VHT station and VHT bandwidth is in use, also set the bandwidth accordingly. Doing this allows us to get rid of the supports_40mhz flag as the HT capabilities now reflect the true capability instead of the current setting. While at it, also fix ieee80211_ht_cap_ie_to_sta_ht_cap() to not ignore HT cap overrides when MCS TX isn't supported (not that it really happens...)

Treat a single connected STA in PSM as a slow link and regulate Tx speed according to slow link priority/stop thresholds.

2012-12-11wlcore/wl18xx: change priority calculations for linksArik Nemtsov
Update the 18xx FW status private part to include Tx related link priorities. Introduce new HW ops to determine link priority per chip family. For 18xx the changes are: - Suspended links are at most low priority and Tx for them is stopped beyond the suspend threshold. - Active links now get their thresholds directly from FW - There's a new "stop" threshold for active links, at which point a link stops receiving new packets. Update the min 18xx FW version required to make sure suspended links bitmap is advertised by the FW. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

wl->num_rx_desc was mistakenly initialized with WL18XX_NUM_TX_DESCRIPTORS but it should use WL18XX_NUM_RX_DESCRIPTORS instead.

2012-12-11wlcore: set 5Ghz probe-req template for DFS channelsArik Nemtsov
Even passive scans on DFS channels require us to send probe requests, so configure the probe-req in this case. Also use this opportunity to prevent the code from crashing in case no SSIDs are sent from above. This will likely happen in the DFS case introduced. Even a passive scan might need the probe request configured because of DFS channels. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-12-11wlcore: increase scan dwell times if no activityEyal Shapira
There's a limit on scan dwell times of max 30ms in order to avoid degrading voip traffic which could be going on while scanning. However these dwell times increase the chance of missing out on nearby APs leading to partial scan results. Allow configuration of longer dwell times in case there no active interface (i.e. no STA associated or AP up).

ACX_PEER_CAP command is just ACX_PEER_HT_CAP, but allows configuring the peer's support rates as well. this is needed because we start the station role when the remote rates are not known yet. the two commands should be unified in future fw versions, but for now add a new set_peer_cap per-hw op, that will use ACX_PEER_CAP for 18xx, and ACX_PEER_HT_CAP for 12xx.

2012-12-05wlcore: improved Tx scheduling algorithmArik Nemtsov
Prioritize EDCA by choosing the AC before anything else. Use the fast/slow link bitmap in FW to improve the scheduling algorithm for the multi-link scenario. Set packet thresholds to determine if a given link is high or low priority according to its speed. A slow link will be given high priority if the amount of packets queued for it in the FW is lower than the slow-threshold. Similarly, a fast link will be given high priority if the number of its packets queued in FW is smaller than the high-threshold. The improved algorithm: 1. Choose optimal AC according to FW utilization 2. Traversing the VIFs in a round-robin fashion, try to choose a high priority link. Links are traversed in a round-robin fashion inside a VIF. 3. If no high priority links are found, choose the first non-empty (low priority) link found in the round robin.

2012-11-28wlcore: add new reg-domain configuration commandVictor Goldenshtein
In 18xx the calibration process of the PHY Cortex domain requires to perform an active calibration of the channel before it can be used for transmission. To fulfill world wide regulatory restrictions, fw should be always synchronized/updated with current CRDA configuration. Add a new "CMD_DFS_CHANNEL_CONFIG" command to update the fw with current reg-domain, this command passes a bit map of channels that are allowed to be used for transmission. The driver shall update the fw during initialization and after each change in the current reg-domain configuration. The driver will save the channel number of incoming beacons during the scan process, as they might be a result of the passive scan on "IEEE80211_CHAN_PASSIVE_SCAN" channel and will update the fw accordingly once the scan is finished, the purpose of this is to be ready in case of the authentication request on one of these disabled (uncalibrated) channels. The new command requires to wait for the fw completion event "DFS_CHANNELS_CONFIG_COMPLETE_EVENT". No scan commands (including the sched scan) can be executed concurrently with the "CMD_DFS_CHANNEL_CONFIG", wl->mutex ensures that.

Use some common functions as much as possible (e.g. for setting scan channels), but split scan.c into chip-specific scan.c files, each implementing its own scan mechanism. (in other words - move most of the current wlcore's scan.c into wl12xx, and implement a similar mechanism in 18xx, according to the new api) New wlcore ops are introduced in order to call the chip-specific scan functions. The template indices used for each scan (regular/scheduled) are also different between the chips, so set the correct indices used for each scan type after identifying the chip.

Adding mutex_lock()/ps_elp_wakeup() calls is not enough, as wl18xx_set_key() calls wl1271_tx_flush() which can't be called while the mutex is taken. Add the required calls to wlcore_op_set_key, but limit the queues_stop and flushing to the only encryption types in which a spare block might be needed (GEM and TKIP).
