2009-03-27b43: fix b43_plcp_get_bitrate_idx_ofdm return typeLorenzo Nava
This patch fixes the return type of b43_plcp_get_bitrate_idx_ofdm. If the plcp contains an error, the function return value is 255 instead of -1, and the packet was not dropped. This causes a warning in __ieee80211_rx function because rate idx is out of range.

2009-03-27b43: Mask PHY TX error interrupt, if not debuggingMichael Buesch
This masks the PHY TX error interrupt, if debugging is disabled. Currently we have a bug somewhere which triggers this interrupt once in a while. (Depends on the network noise/quality). While this is nonfatal, it scares the hell out of users and we frequently receive bugreports that incorrectly identify this error message as the reason. There's another problem with this. The PHY TX error interrupt is protected with a watchdog that will restart the device if it keeps triggering very often. This is used to fix interrupt storms from completely broken devices. However, this watchdog might trigger in completely normal operation. If the TX capacity of the card is saturated, the likeliness of the watchdog triggering increases, as more TX errors occur. The current threshold for the watchdog is 1000 errors in 15 seconds. This patch adds a workaround for the issue by just enabling the interrupt if debugging is disabled (by Kconfig or by modparam). This has the downside that real fatal PHY TX errors are not caught anymore. But this is nonfatal due to the following reasons: * If the card is not able to transmit anymore, MLME will notice anyway. * I did _never_ see a real fatal PHY TX error in a mainline b43 driver. * It does _not_ result in interrupt storms or something like that. It will simply result in a stalled card. It can be debugged by enabling the debugging module parameter. Signed-off-by: Michael Buesch <mb@bu3sch> Signed-off-by: John W.

2009-03-05b43: Pass more RX flags to mac80211Michael Buesch
This changes the RX handler to pass more status flags to mac80211. It also changes part of the drop policy, if bad frames were requested. (Note that currently mac80211 will throw a WARN_ON in that case. But nothing bad will happen). This also removes some obsolete unused timestamping code.

2009-02-27b43: Add slot count compiletime assertionMichael Buesch

Linville <linville@tuxdriver.com>
2009-02-27b43: Optimize DMA buffersMichael Buesch
In the old days we used one slot per frame. But when we changed that to 2, we didn't raise the overall slot count. Which resulted in an effective division of two to the number of slots. Double the number of TX slots, so we have an effective hardware queue of 128 frames per QoS queue. Also optimize the TX header cache handling. We don't need a cached TX header for slots that will never carry an actual header. So we reduce the memory consumption of the cache by 50%. So as a net result we end up with more or less the same memory usage before and after this patch (except a few tiny meta structures), but have twice the number of TX slots available.

2009-02-27b43: Fix DMA buffer size handlingMichael Buesch
This fixes hidden bugs in the size handling of the DMA buffers.

2009-01-29b43: Dynamically control log verbosityMichael Buesch
Dynamically control the log verbosity with a module parameter. This enables us to dynamically enable debugging messages (or disable info, warn, error messages) via module parameter or /sys/module/b43/parameters/verbose. This increases the module size by about 3k. But in practice it reduces the module size for the user, because some distributions ship the b43 module with CONFIG_B43_DEBUG set, which increases the module by about 15k. So with this patch applied, distributions should really _disable_ CONFIG_B43_DEBUG. There is no reason to keep it in a production-release kernel. So we have a net reduction in size by about 12k. This patch also adds a printk of the wireless core revision, so people don't have to enable SSB debugging to get the wireless core revision.

2009-01-29b43: Automatically probe for opensource firmwareMichael Buesch
First probe for proprietary firmware and then probe for opensource firmware. This way around it's a win-win situation. 1) If proprietary fw is available, it will work. 2) If opensource firmware is available, but no proprietary (Distros can only ship open fw) it might work. 3) If both open and proprietary are available, it will work, because it selects the proprietary. We currently don't prefer the open fw in this case, because it doesn't work on all devices. It would introduce a regression otherwise. The remaining FIXMEs in this patch are harmless, because they only matter on multiband devices, which are not implemented yet anyway.
