2012-04-12wireless/wl12xx/wl1251: move TI WLAN modules to a common ti subdirectoryLuciano Coelho36-22640/+0
Move wl12xx and wl1251 modules into a new drivers/net/wireless/ti directory. Add a TI WLAN Kconfig option and Makefile to support this change. Signed-off-by: Luciano Coelho <coelho@ti.com> Cc: John W. Linville <linville@tuxdriver.com>
2012-04-10wl12xx: increase scan timeout to 30sEyal Shapira1-1/+1
In certain scenarios involving sched scan + normal scan + COEX scan could take longer than 10s and this triggers a recovery where it shouldn't. Increase the timeout to avoid that. Signed-off-by: Eyal Shapira <eyal@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-10wl12xx: adaptive sched scan dwell timesEyal Shapira3-18/+60
Set the dwell times for sched scan according to the number of probe requests which are going to be transmitted. This should fix the too short dwell time problem which prevented some of the probe requests from being transmitted in cases of high number of SSIDs (10+) to be actively sched scanned. However, in the common case of having up to 1-2 SSIDs that require active scan, the dwell time would be kept to a minimum which should conserve power. This is important as sched scan also runs periodically while the host is suspended and there's great importance to keep power consumption as low as possible.

2012-04-10wl12xx: fix a memory leak of probereq template upon recoveryEyal Shapira1-0/+2
wlvif->probereq is zeroed when adding an interface but the skb pointed to isn't freed when the interface is removed. This would lead to a mem leak on every recovery. Fix it by freeing the skb when removing the interface. Signed-off-by: Eyal Shapira <eyal@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

2012-04-10wl12xx: fix race between suspend/resume and recoveryEyal Shapira1-17/+12
The iteration on the wlvif list in wl1271_op_resume/suspend was perfomed before locking wl->mutex which would lead to a kernel panic in case a recovery was queued at the same time and would delete the wlvifs from the list.

2012-04-10wl12xx: set do_join on BSS_CHANGED_ASSOCEliad Peller1-5/+2
wl12xx sets the do_join flag (which later starts the sta role) when the bssid was changed and the sta is associated. However, this no longer happens after the "mac80211: remove spurious BSSID change flag" patch. Fix it by setting the do_join flag on BSS_CHANGED_ASSOC (for IBSS, do_join is already set on BSS_CHANGED_IBSS) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-09wireless: rename ht_info to ht_operationJohannes Berg1-1/+1
Since some of the HT code pre-dates 802.11n-2009 some names are wrong. The one that bothers me most is that "HT operation" is called "HT information" in our code and that causes confusion. Rename "HT information" to "HT operation" and also the control_chan field to primary_chan to match the name used in the spec.

2012-03-08wl12xx: implement SW Tx watchdogArik Nemtsov7-0/+135
Track freed FW blocks during Tx. If no blocks were freed during a predefined timeout, initiate a HW recovery. This helps in situations when the FW watchdog fails. Don't trigger recovery during activities that can temporarily stop Tx. This includes: - scanning - buffering packets for sleeping stations (AP role) - ROC on any role Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

2012-03-05wl12xx: avoid bug_on_recovery during fw switchEliad Peller2-1/+5
Add a flag to indicate we initiated a recovery work on purpose, in order to avoid triggering BUG() (when the bug_on_recovery module param was set). Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-03-05wl12xx: configure the correct beacon_intervalEliad Peller1-0/+1
We didn't update the beacon interval on association (or on a change notification when working as sta), so the default interval (100ms) was always used. Update the beacon interval according to the bss_conf before starting the sta role (on association). Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-03-05wl12xx: don't allow scanning while device is in ROCEliad Peller1-4/+2

2012-03-05wl12xx: don't handle change_channel while associatedEliad Peller1-27/+14
Currently, CHANGE_CHANNEL indication while associated is considered as roaming attempt. However, with the new auth/assoc redesign, we no longer have to handle this case, so remove it. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-03-05wl12xx: set correct vif type in change_interface callbackEliad Peller1-1/+1
In some cases, the wrong vif type was set in the change_interface callback (P2P_CLIENT/P2P_GO instead of STA/AP) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-03-05wl12xx: increment session_counter for device role as wellEliad Peller1-1/+1

2012-03-05wl12xx: set authorized AP on sta_state notificationEliad Peller2-97/+23
wl12xx currently looks for AP authorization by registering a netdev notifier and waiting for the IF_OPER_UP notification, which is quite cumbersome. Use the newly introduced sta_state callback (waiting for assoc -> auth notification) instead, in order to simplify it.

2012-03-05wl12xx: implement sta_state callbackEliad Peller1-55/+82
Implement sta_state callback instead of the sta_add/remove callbacks. Update the fw regarding peer state and ht caps only after the station was authorized. Otherwise, the fw might try establishing BA session before the sta is authorized. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-03-05wl12xx: consider bss_conf->idle instead of hw->conf.flagsEliad Peller1-2/+1

2012-03-05wl12xx: don't start dev role on ibss vifsEliad Peller1-4/+2
device role is used for scanning and sending packets before connection. however, since we don't need to send packets before ibss creation, there is no need to start the device on idle-off. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

2012-02-28wl12xx: flush all Tx queues on tx_flush timeoutArik Nemtsov1-0/+7
Ensure our queues are empty at the end of a tx_flush(), in case we timeout on passively waiting for them. This makes sure no left-overs are transmitted when we are on the wrong channel. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-28wl12xx: avoid starving the system hlidArik Nemtsov1-4/+13
Re-factor the Tx scheduler so that the system_hlid is taken into account before restarting an iteration over the wlvifs. Previously this hlid had a lower priority and would starve if some wlvif had many packets. In addition avoid iterating over wlvifs past last_wlvif when performing the a second pass. If we had packets in those wlvifs they would have been found earlier. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-28wl12xx: reset link Tx queues when freeing itArik Nemtsov3-4/+17
Before, the link was first freed (invalidating it in the map), and later on vif removal, all valid wlvif-related links were reset. Since these links were already invalid, we failed to reset them. The bug was made worse by op_stop, which set the tx_queue_count to 0 arbitrarily. This resulted in a negative tx_queue_count in some scenarios. Fix this by resetting the Tx-queues of a link when freeing it. Add a WARN_ON and reset all link Tx-queues in op_stop, to avoid a negative tx_queue_count.

2012-02-28wl12xx: change bits in the link_map under spin lockArik Nemtsov1-0/+9
These bits are used in op_tx to determine if a packet should be dropped. As such we should use the spin lock to sync the state. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-28wl12xx: set the ELP entry delay to the FW dyn-ps timeoutArik Nemtsov1-3/+1
With PSM handled in FW, the checks in wl1271_elp_work() are always true. Thus during active traffic we constantly enter and exit ELP (many times per second). As each ELP exit takes ~10ms, this can have an adverse effect on throughput and interactivity. Set the ELP timeout to the dyn-ps timeout. This period is longer and avoids the above problem. It also makes sense to stay out of ELP while we are awake on the network, to minimize delays in Tx/Rx. The same thing was done by the mac80211 dynamic-ps mechanism before the FW DPS changes.

2012-02-15wl12xx: enter forced-psm on fw changeEliad Peller1-0/+15
Enter forced psm when changing fw, in order to make the sta a bit more disconnection-persistent. (DPM doesn't know about the incoming recovery, so it won't enter psm by itself) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-02-15wl12xx: dynamically change fw according to number of active rolesEliad Peller4-13/+124
wl12xx uses different fw for single-role and multi-role scenarios (due to lack of space, some of the fw advanced features are disabled in the multi-role fw). Add checks on add_interfae and remove_interface in order to determine whether a fw switch is needed (and initiate recovery in this case).

2012-02-15wl12xx: declare support for hw scan while idleEliad Peller2-18/+2
By allowing hw scan while idle, we no longer need the redundant ROC/CROC that are done on idle off/on, which helps simplifying the state machine of the driver.

2012-02-15wl12xx: consider encryption and QoS in auto arp templateEliad Peller9-35/+117
When configuring the arp response template, and encryption is enabled, we should add some space and set the protected flag bit in the fc. In order to track the encryption type, set wlvif->encryption_type when setting an encryption key, and reconfigure the arp response. Clear this field on wl1271_join, as keys have to be re-configured anyway after a join command. Similarly, track whether QoS is configured.
