* wl1271: Disable host TX rate controlJuuso Oikarinen2010-03-091-0/+2
| | | | | | | | | Disable host TX rate control. The wl1271 firmware is already managing rate control, so this eliminate unnecessary host processing.

* wl1271: Clean up TX security sequence number handlingJuuso Oikarinen2010-03-091-8/+2
| | | | | | | | | Instead of managing the TX security sequence number as two variables, use one 64 bit variable. This greatly simplifies the handling of the number.

* wl1271: Update TX packet life time handling with higher resolution timeJuuso Oikarinen2010-03-091-2/+5
| | | | | | | | | | This patch uses a higher precision timer to synchronize with the firmware clock. Improved precision is needed as on some platforms a jiffy may be up to tens of milliseconds, and the required precision is closer to TU's.

| | | | | | | | | | The queue stopping/waking functionality was broken in a way that could cause huge latencies in TX transfers and even cause the TX to stall in the right circumstances.

* wl1271: Improvements to the TX pathJuuso Oikarinen2010-03-091-15/+23
| | | | | | | | | | | | - Fix a TX result overflow problem that was present in the TX path and visible with at least linksys AP's (probably any AP with high throughput capability.) - Optimize TX by writing FW trigger for a group of TX frames instead of each and every frame. - Slightly optimize the TX path code.

* wl1271: fix endianess issuesLuciano Coelho2009-10-271-9/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We were not handling endianess correctly. The wl1271 chip runs on little-endian values. This patch makes sure that all the communication with the wl1271 firmware is done in little-endian by using cpu_to_le* and le*_to_cpu where appropriate. Also, all the struct definitions for data exchanged with the firmware has been changed to use __le16/32 types instead of u16/32. This fixes a few sparse warnings, such as these: drivers/net/wireless/wl12xx/wl1271_cmd.c:554:42: warning: incorrect type in assignment (different base types) drivers/net/wireless/wl12xx/wl1271_cmd.c:555:42: warning: incorrect type in assignment (different base types) drivers/net/wireless/wl12xx/wl1271_cmd.c:577:58: warning: incorrect type in assignment (different base types) drivers/net/wireless/wl12xx/wl1271_cmd.c:579:58: warning: incorrect type in assignment (different base types) drivers/net/wireless/wl12xx/wl1271_cmd.c:676:18: warning: incorrect type in assignment (different base types) drivers/net/wireless/wl12xx/wl1271_cmd.c:787:22: warning: incorrect type in assignment (different base types) drivers/net/wireless/wl12xx/wl1271_cmd.c:789:21: warning: incorrect type in assignment (different base types) drivers/net/wireless/wl12xx/wl1271_tx.c:98:47: warning: incorrect type in argument 1 (different base types) drivers/net/wireless/wl12xx/wl1271_acx.c:932:32: warning: incorrect type in assignment (different base types) drivers/net/wireless/wl12xx/wl1271_boot.c:191:32: warning: incorrect type in argument 1 (different base types) drivers/net/wireless/wl12xx/wl1271_boot.c:197:38: warning: incorrect type in argument 1 (different base types) drivers/net/wireless/wl12xx/wl1271_boot.c:199:37: warning: incorrect type in argument 1 (different base types) drivers/net/wireless/wl12xx/wl1271_init.c:255:40: warning: incorrect type in assignment (different base types) drivers/net/wireless/wl12xx/wl1271_init.c:275:53: warning: incorrect type in assignment (different base types) Reported-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Luciano Coelho <luciano.coelho@nokia.com> Reviewed-by: Juuso Oikarinen <juuso.oikarinen@nokia.com> Signed-off-by: John W.

* wl1271: add wl1271 driver filesLuciano Coelho2009-08-141-0/+378
This driver supports the wl1271 chipset from Texas Instruments based on the WiLink(tm) 6.0 mobile platform. Support for wl1273 should be relatively easy to add. This chipset is designed for embedded devices, with good powersaving capabilities. The wl1271 chipset is the successor of wl1251 and supports the 802.11b/g/n standards, but currently this driver supports only b/g.
