Hi Dave,

here are two more bug fixes for the Bluetooth subsystem. Both are workarounds for either broken implementations or broken hardware.

Regards

Marcel

[Bluetooth] Correct SCO buffer size for another Broadcom chip

The SCO buffer size values on IBM/Lenovo ThinkPad laptops with a Bluetooth chip from Broadcom are wrong. The USB Bluetooth driver has to set a quirk to correct the SCO buffer size values.

[Bluetooth] Correct RFCOMM channel MTU for broken implementations

Some Bluetooth RFCOMM implementations try to negotiate a bigger channel MTU than we can support for a particular session. The maximum MTU for a RFCOMM session is limited through the L2CAP layer. So if the other side proposes a channel MTU that is bigger than the underlying L2CAP MTU, we should reduce it to the L2CAP MTU of the session minus five bytes for the RFCOMM headers.

Hi Dave,

here are two more bug fixes for the Bluetooth subsystem. Both are workarounds for either broken implementations or broken hardware.

we've seen a bunch of buggy USB Bluetooth devices lately and I have three more patches to workaround various issues. I also re-based the tree to 2.6.18-rc2 and pushed the additional changes. Please pull and forward to Linus as soon as possible.

Regards

Marcel

[Bluetooth] Enable SCO support for Broadcom HID proxy dongle

The Broadcom dongles with HID proxy support actually support SCO over HCI if the SCO buffer size values are corrected. So instead of disabling the SCO support, mark this dongle with the quirk for the Bluetooth core to correct the wrong buffer size values.

[Bluetooth] Add quirk for another broken RTX Telecom based dongle

This patch disables the ISOC transfers for another broken RTX Telecom based USB dongle. Starting the USB ISOC transfers only ends in a burst of error messages for invalid SCO packets on connection handle 0.

[Bluetooth] Correct SCO buffer size for Belkin devices

The Belkin F8T012 and F8T013 devices are both based on a Bluetooth chip from Broadcom and their SCO buffer size values are wrong. The Bluetooth core should correct these values.
