b43: Fix some TX/RX locking issues

2008-05-10T04:40:49+00:00

commit 21a75d7788f4e29b6c6d28e08f9f0310c4de828d upstream.

This fixes some TX/RX related locking issues.
With this patch applied, some of the PHY transmission errors are fixed.

b43: Fix dual-PHY devices

2008-05-10T04:40:48+00:00

commit 2e35af143a1380173ba292e48e9b4913ef16b4ee upstream

This fixes operation of dual-PHY (A/B/G) devices.
Do not anounce the A-PHY to mac80211, as that's not supported, yet.

b43: Workaround DMA quirks

2008-05-01T21:44:37+00:00

commit 1033b3ea11820ea1fb1b877207bd6724e9aaedc3 upstream

Some mainboards/CPUs don't allow DMA masks bigger than a certain limit.
Some VIA crap^h^h^h^hdevices have an upper limit of 0xFFFFFFFF. So in this
case a 64-bit b43 device would always fail to acquire the mask.
Implement a workaround to fallback to lower DMA mask, as we can always
also support a lower mask.

b43: Workaround invalid bluetooth settings

2008-05-01T21:44:36+00:00

commit 1855ba7812dbd294fcfc083dc7d3b14d3b1f38db upstream.

This adds a workaround for invalid bluetooth SPROM settings
on ASUS PCI cards.
This will stop the microcode from poking with the BT GPIO line.
This fixes data transmission on this device, as the BT GPIO line
is used for something TX related on this device
(probably the power amplifier or the radio).
This also adds a modparam knob to help debugging this in the future,
as more devices with this bug may show up.

b43legacy: fix DMA mapping leakage

2008-04-15T19:04:36+00:00

This fixes a DMA mapping leakage in the case where we reject a DMA buffer
because of its address.
The patch by Michael Buesch has been ported to b43legacy.

ssb: Fix usage of struct device used for DMAing

2008-04-15T19:04:35+00:00

This fixes DMA on architectures where DMA is nontrivial, like PPC64.
We must use the host-device's (PCI) struct device for any DMA
operation instead of the SSB device. For this we add a new
struct device pointer to the SSB device structure that will always
point to the right device for DMAing.

Without this patch b43 and b44 drivers won't work on complex-DMA
architectures, that for example need dev->archdata for DMA operations.

b43legacy: fix initvals loading on bcm4303

2008-04-15T19:04:34+00:00

This allows for the correct initial values to be uploaded to bcm4303
devices. It should be correct, but I can't reliably test this as I suspect
there's something going wrong with an hardware rfkill switch on my laptop.
Please test.

rtl8187: Add missing priv->vif assignments

2008-04-15T18:51:57+00:00

This adds missing priv->vif assignments after "mac80211: don't use
interface indices in drivers" change. As rtl8180, rtl8187 also needs
priv->vif to be set, as without this an oops can happen in rtl8187_tx
function (priv->vif is passed to ieee80211_rts_duration).
