wl1271: Change wl12xx Files Names

2010-11-22T14:45:09+00:00

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 Signed-off-by: Luciano Coelho

wireless/wl1271: remove redundant if-statement v2

wl1271_ps_elp_sleep() is void and cannot return a value. Signed-off-by: Nicolas Kaiser Reviewed-by: Luciano Coelho Signed-off-by: Luciano Coelho

wl1271: Increase connection reliability

2010-09-28T09:30:06+00:00

This patch improves connection reliability by choosing the lowest basic rate for null-func frames (which increases their range, as the firmware does not do rate fall-back for null-func frames.) Also, increase the PSM entry retry-counter. Signed-off-by: Juuso Oikarinen Reviewed-by: Teemu Paasikivi Tested-by: Tuomas Katila Signed-off-by: Luciano Coelho

wl1271: Fix work cancelling when shutting down the driver

2010-09-28T09:30:03+00:00

The work cancelling has had several hazards, ranging from potentially executing work after the driver is in OFF state, to executing work after the driver and relevant memory structures are already removed. Fix these. Signed-off-by: Juuso Oikarinen Reviewed-by: Teemu Paasikivi Signed-off-by: Luciano Coelho

wl1271: Reduce rate used for last PSM entry attempt

2010-09-28T09:15:11+00:00

This patch reduces the rate of the null-func used to enter PSM on the last retry as precaution. Signed-off-by: Juuso Oikarinen Reviewed-by: Luciano Coelho Signed-off-by: Luciano Coelho

wl1271: rewritten scanning code

2010-07-08T20:42:09+00:00

This patch is a complete rewrite of the scanning code. It now includes a state machine to scan all four possible sets of channels independently: 2.4GHz active, 2.4GHz passive, 5GHz active and 5GHz passive. The wl1271 firmware doesn't allow these sets to be mixed, so up to several scan commands have to be issued. This patch also allows scanning more than 24 channels per set, by breaking the sets into smaller parts if needed (the firmware can scan a maximum of 24 channels at a time). Previously, the scanning code was erroneously scanning all channels possible actively, not complying with the CRDA values. This is also fixed with this patch.

wl1271: moved scan operations to a separate file

2010-07-08T20:41:58+00:00

The scanning code is going to get a bit more complex, with proper support for active/passive scans together with 2.4GHz and 5GHz. In the future, also a new type of scan (periodic scan) will be added. When all this is implemented, the code is going to be much more complex, so we'd better separate it into a separate file. This patch doesn't have any impact on functionality.

wl1271: Update interface to temporarily disable dynamic PS

wl1271: Disable dynamic PS based on BT co-ext sense events

2010-07-08T20:35:51+00:00

This patch requests mac80211 to disable dynamic PSM based on sense events coming from the firmware. Effectively, whenever there is bluetooth traffic, the mac80211 is forced into full PSM mode.

wl1271: Work around AP's with broken ps-poll functionality

2010-07-08T20:35:51+00:00

Some AP's (such as Zyxel Prestige 600) have totally broken ps-poll functionality. When powersave is enabled, these AP's will set the TIM bit for a STA in beacons, but when the STA responds with a ps-poll, the AP does not respond with data. The wl1271 firmware is able to send an indication to the host, when this problem occurs. This patch adds implementation, which temporarily disables power-save in response to this indication, allowing the AP to transmit whatever data it has buffered for the STA / whatever data is inbound at that time. This patch does not make these AP's work reliably in PSM, but improves the chances of inbound data getting through. The side effect of this patch is increased power consumption when using a faulty AP. Signed-off-by: Juuso Oikarinen Reviewed-by: Teemu Paasikivi Signed-off-by: Luciano Coelho Signed-off-by: John W.
