* Bluetooth: Add native RFKILL soft-switch support for all devicesMarcel Holtmann2009-06-08
| | | | | | | | With the re-write of the RFKILL subsystem it is now possible to easily integrate RFKILL soft-switch support into the Bluetooth subsystem. All Bluetooth devices will now get automatically RFKILL support. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
* Bluetooth: Remove unused and unneeded support in virtual driverMarcel Holtmann2009-06-08
| | | | | | | | The virtual driver implements fasync and ioctl support, but it is not used and unneeded due to its constraints via the Bluetooth core layer. So too just make the driver simpler, remove support for both of them. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
* Bluetooth: Remove BKL from open callback of virtual driverMarcel Holtmann2009-06-08
| | | | | | | | The BKL push down added some BKL into the open callback of the virtual driver. The driver is really simple and need no such locking and so just remove it. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
* Bluetooth: Use wait_event_interruptible for virtual driverMarcel Holtmann2009-06-08
| | | | | | | | The virtual driver still uses a home grown way of waiting for events and so just replace it with wait_event_interruptible. And while at it remove the useless access_ok() checks. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
* Bluetooth: Use only MISC_DYNAMIC_MINOR for virtual driverMarcel Holtmann2009-06-08
| | | | | | | | Allowing to specify a specific misc minor number for the virtual driver is pretty much useless and nobody is using this feature. So just remove it and use MISC_DYNAMIC_MINOR all the time. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
* Bluetooth: Remove pointless endian conversion helpersMarcel Holtmann2009-06-08
| | | | | | | | The Bluetooth source uses some endian conversion helpers, that in the end translate to kernel standard routines. So remove this obfuscation since it is fully pointless. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

* ixgbe: Add FW detection and warning for 82599 SFP+ adaptersPeter P Waskiewicz Jr2009-06-07
| | | | | | | | | | | | | | | | 82599 has a FW running that helps manage the internal SFI PHY. There are also a number of pre-production samples of these SFI-based devices in the field. This patch adds a check to look for the firmware running on all SFP+ based adapters, and displays a warning to the system log if a pre-production adapter is identified. The driver will continue loading though, with no functional degradation. Also remove an old function prototype from ixgbe_82599.c that isn't being used.

* ixgbe: Add Flow Director init and modify functions for 82599Peter P Waskiewicz Jr2009-06-07
| | | | | | | | | | | | | This patch adds the functions for ixgbe to initialize Flow Director. It also has the function APIs to add Flow Director filters from the base driver. This also includes ATR, Application Targeted Routing, which is a feature set of Flow Director. This is the hash-based mechanism to automatically identify flows and add filters based on the hash, and direct the Rx of that flow back to that same CPU.

* ixgbe: move tx processing into NAPI contextAlexander Duyck2009-06-07
| | | | | | | | | | | This patch moves the tx cleanup processing out of the MSI-X interrupt processing and gives it it's own napi routine. This allows the driver to process TX cleanup in a polling context instead of in an interrupt context which prevents TX from starving RX.

| | | | | | | | | | | The v_idx value was being used as both a bitmask and an index. This change makes it so that the q_vector contains the index and allows for much of the code to be simplified since disabling a q_vector involves only clearing one bit in the interrupt bitmask.

| | | | | | | | | | | This patch changes the driver so that it uses rx_buffer_info->dma to determine if it needs to unmap the page instead of sh_info->nr_frags.

* ixgbe: Harden the 82599 multispeed fiber autotry mechanismPeter P Waskiewicz Jr2009-06-07
| | | | | | | | | | | | | | | 82599 supports multispeed fiber optical modules (10Gbps/1Gbps). Some scenarios can cause the autotry mechanism to not negotiate link properly. What needs to happen is the driver must flap the Tx laser to induce an Rx Loss of Signal on the link partner. This will restart the autotry mechanism to get link into a known state. The software definable pin (SDP) 3 on the 0x10fb NIC is wired to cause a Tx LOS event, which triggers the Rx LOS we require.

* ixgbe: Change the 82599 PHY DSP restart logicPeter P Waskiewicz Jr2009-06-07
| | | | | | | | | | | | | When reprogramming the 82599 analog PHY to either SFI optical or Direct Attach Twinax, we need to restart the DSP in the PHY. The current method can cause contention with our FW which is managing PHY state, and will cause unexpected link flaps. This patch fixes the DSP restart by issuing an AN_RESTART in the MAC, which will properly propagate the DSP restart to the PHY. This ensures we don't collide with the FW.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch fixes the bug at http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1903 when SW rfkill is invoked by 'iwconfig txpower off', the existing connection disassociates and led off command is sent to the device which returns error as rfkill is 'true'. Patch fixes this by just avoiding sending the led off/on command when disassociated. The main purpose of the led_disassociate callback is to start or stop the blinking. There are three states in led 1) Always on when radio is on 2) Always off when radio is off 3) blink when associated and if there is some traffic. In this callback 'allow_blinking' needs to be set false when associated, as LED will be always on.
