* wl12xx: add stop_scan commandEliad Peller2011-07-051-0/+27
| | | | | | | define wl1271_scan_stop() to cancel an ongoing hw scan. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
* wl12xx: Avoid recovery while one is already in progressIdo Yariv2011-06-271-1/+1
| | | | | | | | | | During recovery work commands sent to the FW could fail and schedule additional recovery work. Since the chip is going to be powered off, avoid recursive recoveries.

* wl12xx: split channel array per band in sched_scanLuciano Coelho2011-06-271-32/+29
| | | | | | | | | The firmware, in practice, treats the channels in three separate blocks, one for each band (bg, a and j). Instead of using a single array and doing some magic with indices, split the array in 3 to make it more readable. Signed-off-by: Luciano Coelho <coelho@ti.com>
* wl12xx: fix oops in sched_scan when forcing a passive scanLuciano Coelho2011-05-311-3/+8
| | | | | | | | | | | | | | | | Fix kernel oops when trying to use passive scheduled scans. The reason was that in passive scans there are no SSIDs, so there was a NULL pointer dereference. To solve the problem, we now check the number of SSIDs provided in the sched_scan request and only access the list if there's one or more (ie. passive scan is not forced). We also force all the channels to be passive by adding the IEEE80211_CHAN_PASSIVE_SCAN flag locally before the checks in the wl1271_scan_get_sched_scan_channels() function.

* wl12xx: add separate config value for DFS dwell time on sched scanLuciano Coelho2011-05-311-2/+5
| | | | | | | | | | | | | Use a different value for DFS dwell time when performing a scheduled scan. Previously we were using the same value as for normal passive scans. This adds some flexibility between these two different types of passive scan. For now we use 150 TUs for DFS channel dwell time. This may need to be fine-tuned in the future.

* wl12xx: fix DFS channels handling in scheduled scanLuciano Coelho2011-05-311-11/+20
| | | | | | | | | | | | | DFS channels were never getting included in the scheduled scans, because they always contain the passive flag as well and the call was asking for DFS and active channels. Fix this by ignoring the passive flag when collecting DFS channels. Also, move the DFS channels in the channel list before the 5GHz active channels (this was implemented in the FW differently than specified).

* wl12xx: fix passive and radar channel generation for scheduled scanLuciano Coelho2011-05-311-2/+2
| | | | | | | | | | We were comparing bitwise AND results with a boolean, so when the boolean was set to true, it was not matching as it should. Fix this by booleanizing the bitwise AND results with !!. Signed-off-by: Luciano Coelho <coelho@ti.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* wl12xx: prevent sched_scan when not idle or not in station modeLuciano Coelho2011-05-131-0/+6
| | | | | | | | The current firmware only supports scheduled scan in station mode and when idle. To prevent the firmware from crashing, return -EOPNOTSUPP when sched_scan start is called in an invalid state. Signed-off-by: Luciano Coelho <coelho@ti.com>
* wl12xx: implement scheduled scan driver operations and reportingLuciano Coelho2011-05-131-1/+5
| | | | | | | This patch adds the mac80211 operations for scheduled scan and the scheduled scan results reporting. Signed-off-by: Luciano Coelho <coelho@ti.com>
* wl12xx: add scheduled scan structures and commandsLuciano Coelho2011-05-131-0/+233
| | | | | | | Add firmware command structures, definitions and code to to configure, start and stop scheduled scans. Signed-off-by: Luciano Coelho <coelho@ti.com>
* wl12xx: use a bitmask instead of list of booleans in scanned_chLuciano Coelho2011-04-191-7/+10
| | | | | | | | | | | We were using an array of booleans to mark the channels we had already scanned. This was causing a sparse error, because bool is not a type with defined size. To fix this, use bitmasks instead, which is much cleaner anyway. Thanks Johannes Berg for the idea. Signed-off-by: Luciano Coelho <coelho@ti.com>
* wl12xx: wakeup chip from ELP during scanArik Nemtsov2011-03-031-6/+14
| | | | | | | | | | Commands are sometimes sent to FW on scan completion. Make sure the chip is awake to receive them. Sending commands while the chip is in ELP can cause SDIO read errors and/or crash the FW.

* wl1271: Fix setting of the hardware connection monitoring probe-req templateJuuso Oikarinen2010-11-261-0/+4
| | | | | | | | | | | | | | | The probe-request template used in the hardware connection monitoring feature thus far has been an empty one, without the SSID IE and without supported rate IEs. This causes problems with some AP's. Additionally, after connected scans, the template for connection maintenance would remain to be the one last used for scanning - potentially incorrect. Fix these by getting a pre-filled directed probe-request template for the associated-to AP from mac80211.

* wl1271: Change wl12xx Files NamesShahar Levi2010-11-221-0/+307
All files name prefix removed due to the fact that wl12xx driver supports wl1271 and wl1273. Also the definition in Kconfig and header files changed respectively. Signed-off-by: Shahar Levi <shahar_levi@ti.com> Signed-off-by: Luciano Coelho <luciano.coelho@nokia.com>
