* b43: Add definitions for MAC Control registerMichael Buesch2008-01-281-19/+18
| | | | | | | | | This adds some definitions for the MAC Control register and uses them. This basically is no functional change. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* b43: Remove PIO supportMichael Buesch2008-01-281-76/+8
| | | | | | | | | | | | | | | Remove b43 PIO support. DMA works well on all supported devices. There's no reason to use PIO. Additionally, new devices don't support PIO in hardware anymore. b43 PIO support is dead and unused code. After applying this patch please do git rm drivers/net/wireless/b43/pio.h git rm drivers/net/wireless/b43/pio.c to remove the main PIO support code.

* b43: Fix ofdmtab write regressionMichael Buesch2008-01-281-6/+6
| | | | | | | | | | | | | | | | commit f04b3787bbce4567e28069a9ec97dcd804626ac7 introduced a regression for the ofdmtable writing. It incorrectly removed the writing of the high 16bits for a 32bit table write and initialized the direction identifier too late. This patch does also some cleanups to make the code much more readable and adds a few comments, so non rocket scientists are also able to understand what this address caching is all about.

* b43: Changes to enable BCM4311 rev 02 with wireless core revision 13Larry Finger2008-01-281-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | The BCM94311MCG rev 02 chip has an 802.11 core with revision 13 and has not been supported until now. The changes include the following: (1) Add the 802.11 rev 13 device to the ssb_device_id table to load b43. (2) Add PHY revision 9 to the supported list. (3) Change the 2-bit routing code for address extensions to 0b10 rather than the 0b01 used for the 32-bit case. (4) Remove some magic numbers in the DMA setup. The DMA implementation for this chip supports full 64-bit addressing with one exception. Whenever the Descriptor Ring Buffer is in high memory, a fatal DMA error occurs. This problem was not present in 2.6.24-rc2 due to code to "Bias the placement of kernel pages at lower PFNs". When commit 44048d70 reverted that code, the DMA error appeared. As a "fix", use the GFP_DMA flag when allocating the buffer for 64-bit DMA. At present, this problem is thought to arise from a hardware error. This patch has been tested on my system and by Cédric Caumont <icare40@hotmail.com>.

* b43: Fix rfkill radio LEDLarry Finger2007-12-171-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | This fixes Bug #9414 Since addition of the rfkill callback, the LED associated with the off switch on the radio has not worked for several reasons: (1) Essential data in the rfkill structure were missing. (2) The rfkill structure was initialized after the LED initialization. (3) There was a minor memory leak if the radio LED structure was inited. Once the above problems were fixed, additional difficulties were noted: (4) The radio LED was in the wrong state at startup. (5) The radio switch had to be manipulated twice for each state change. (6) A circular mutex locking situation existed. (7) If rfkill-input is built as a module, it is not automatically loaded. This patch fixes all of the above.

* b43: fix shared IRQ race conditionStefano Brivio2007-11-101-7/+10
| | | | | | | | | | | Fix an IRQ race condition in b43. If we call b43_stop_wireless_core(), it will set the status of the device to INITIALIZED and the IRQ handler won't care any longer about IRQs, thus the kernel will disable the IRQ if it's shared (unless we boot it with the 'irqpoll' option). So we must disable IRQs before changing the device status. Signed-off-by: Stefano Brivio <stefano.brivio@polimi.it> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* [PATCH] mac80211: revamp interface and filter configurationJohannes Berg2007-10-101-116/+132
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drivers are currently supposed to keep track of monitor interfaces if they allow so-called "hard" monitor, and they are also supposed to keep track of multicast etc. This patch changes that, replaces the set_multicast_list() callback with a new configure_filter() callback that takes filter flags (FIF_*) instead of interface flags (IFF_*). For a driver, this means it should open the filter as much as necessary to get all frames requested by the filter flags. Accordingly, the filter flags are named "positively", e.g. FIF_ALLMULTI. Multicast filtering is a bit special in that drivers that have no multicast address filters need to allow multicast frames through when either the FIF_ALLMULTI flag is set or when the mc_count value is positive. At the same time, drivers are no longer notified about monitor interfaces at all, this means they now need to implement the start() and stop() callbacks and the new change_filter_flags() callback. Also, the start()/stop() ordering changed, start() is now called *before* any add_interface() as it really should be, and stop() after any remove_interface(). The patch also changes the behaviour of setting the bssid to multicast for scanning when IEEE80211_HW_NO_PROBE_FILTERING is set; the IEEE80211_HW_NO_PROBE_FILTERING flag is removed and the filter flag FIF_BCN_PRBRESP_PROMISC introduced. This is a lot more efficient for hardware like b43 that supports it and other hardware can still set the BSSID to all-ones.
