2011-08-29b43: Fix swatch warningLarry Finger1-1/+4
Swatch reports the following warning for main.c: CHECK drivers/net/wireless/b43/main.c drivers/net/wireless/b43/main.c +4115 b43_wireless_core_stop(7) warn: variable dereferenced before check 'dev' After analysis, this is not a bug, but a false warning. Nonetheless, a cleanup is in order to prevent some future janitor proposing the wrong fix, as I did in my original patch.

2011-08-29b43: Relax requirement for descriptors to be in the DMA zoneLarry Finger1-7/+0
When 64-bit DMA was first used, there were problems with the BCM4311 (14e4:4311). The problem was "fixed" by using the GFP_DMA flag in the allocation of coherent ring descriptor memory. The original problem is now believed to have been due to bugs in the 64-bit DMA implementation in the rest of the kernel, and that those bugs have been fixed. Accordingly, the requirement for the descriptors to be in the DMA zone is relaxed. Bounce buffers are left in the DMA zone.

2011-08-24b43/legacy: Remove firmware IDsMichael Büsch2-8/+1
This removes the "FWxx" ID strings from the b43 and b43legacy drivers. They were once used to match a specific driver revision to a set of firmware files. However, this is hardly useful today. Additionally, the IDs are not updated and maintained properly, so they might mislead users.

We have resolved all the known issues with DMA mode, however some users (or distros) are still forcing PIO mode by config files. Without debugging enabled it's not noticable at all.

2011-08-22b43: reload phy and bss settings after core restartsFelix Fietkau1-5/+37
b43_op_config and b43_op_bss_info_changed apply many settings by directly writing to hardware registers. These settings are lost as soon as the core is restarted and the initvals are reloaded. This was discovered because restarting hostapd led to the beacon interval getting set to ~33s (see https://dev.openwrt.org/ticket/8033 for more information).
