* iwlwifi: split the drivers for agn and legacy devices 3945/4965Wey-Yi Guy2011-02-2173-2083/+30482
| | | | | | | | | | | | | | | | | | Intel WiFi devices 3945 and 4965 now have their own driver in the folder drivers/net/wireless/iwlegacy Add support to build these drivers independently of the driver for AGN devices. Selecting the 3945 builds iwl3945.ko and iwl_legacy.ko, and selecting the 4965 builds iwl4965.ko and iwl_legacy.ko. iwl-legacy.ko contains code shared between both devices. The 3945 is an ABG/BG device, with no support for 802.11n. The 4965 is a 2x3 ABGN device.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Correct channel setting function must be used for AR2317. When I tested ahb patch on bullet2 all seemed to work fine, but it couldn't connect another host (using ibss for example). During an analysis I observed that it's transmitting on another channel. I looked into madwifi code and understood that the problem is in channel setting function. So atheros RF2317 not fully handled in the current ath5k version and must be patched.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DMA latency issue is observed only in Intel pinetrail platforms but in the driver we had a default PM-QOS value of 55.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch fixes: https://bugzilla.redhat.com/show_bug.cgi?id=654599 Many users report very low speed problem on 3945 devices, this patch fixes problem, but only for some of them. For unknown reason, sometimes after hw scanning, device is not able to receive frames at high rate. Since plcp health check may request hw scan to "reset radio", performance problem start to be observable after update kernel to .35, where plcp check was introduced. Bug reporter confirmed that removing plcp check fixed problem for him.

Features of the rewrite include: * handles undocumented "0x0000" word at the start of the frequency table. (Affected some early? DELL 1450 USB devices and my Symbol 5GHz miniPCI card.) * supports more than just one reference point per band. (Also needed for the Symbol card.) * ships with default values in case the eeprom data is damaged, absent or unsupported.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some channel indices of the low 5GHz band clash with those of the 2.4GHz band. Therefore we should go with the channel's center frequency. Signed-off-by: Christian Lamparter <chunkeey@googlemail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

Make asynchronous zd_usb_iowrite16v_async available outside zd_usb.c and use where possible. This lower CPU usage from ~10% to ~2% on Intel Atom when running AP-mode with 100 TU beacon interval.

This patch makes zd_usb_iowrite16v use asynchronous urb submit within zd_usb.c. zd_usb_iowrite16v_async_start is used to initiate writing multiple commands to device using zd_usb_iowrite16v_async. Each URB is delayed and submitted to device by next zd_usb_iowrite16v_async call or by call to zd_usb_iowrite16v_async_end. URBs submitted by zd_usb_iowrite16v_async have URB_NO_INTERRUPT set and last URB send by zd_usb_iowrite16v_async_end does not. This lower CPU usage when doing writes that require multiple URBs.

* | | | zd1211rw: correct use of usb_bulk_msg on interrupt endpointsJussi Kivilinna2011-02-141-12/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | zd1211rw is using usb_bulk_msg() with usb_sndbulkpipe() on interrupt endpoint. However usb_bulk_msg() internally corrects this and makes interrupt URB. It's better to change usb_bulk_msgs in zd1211rw to usb_interrupt_msg for less confusion.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Beaconing should be disabled before stopping beacon queue. Not doing so could queue up beacons in hw that causes failure to stop Tx DMA, due to pending frames in hw and also unnecessary beacon tasklet schedule.
