Some onboard BT chips (e.g. Marvell 8997) contain a wakeup pin that can be connected to a gpio on the CPU side, and can be used to wakeup the host out-of-band. This can be useful in situations where the in-band wakeup is not possible or not preferable (e.g. the in-band wakeup may require the USB host controller to remain active, and hence consuming more system power during system sleep). The oob gpio interrupt to be used for wakeup on the CPU side, is read from the device tree node, (using standard interrupt descriptors). A devcie tree binding document is also added for the driver. The compatible string is in compliance with Documentation/devicetree/bindings/usb/usb-device.txt Signed-off-by:

If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro.

Current behaviour of "mirred redirect" action (forward) offload is a bit odd. For matched packets the action forwards them to the desired destination, but it also lets the packet duplicates to go the original way down (bridge, router, etc). That is more like "mirred mirror". Fix this by using PBS type which behaves exactly like "mirred redirect". Note that PBS does not support loopback mode.

Yuval Mintz says: ==================== qed*: Add support for PTP This patch series adds required changes for qed/qede drivers for supporting the IEEE Precision Time Protocol (PTP). Changes from previous versions: v7: Fixed Kbuild robot warnings. v6: Corrected broken loop iteration in previous version. Reduced approximation error of adjfreq. v5: Removed two divisions from the adjust-frequency loop. Resulting logic would use 8 divisions [instead of 24]. v4: Remove the loop iteration for value '0' in the qed_ptp_hw_adjfreq() implementation. v3: Use div_s64 for 64-bit divisions as do_div gives error for signed types. Incorporated review comments from Richard Cochran. - Clear timestamp resgisters as soon as timestamp is read. - Use shift operation in the place of 'divide by 16'. v2: Use do_div for 64-bit divisions. ==================== Acked-by:Richard Cochran <richardcochran@gmail.com> Signed-off-by:

The usage count function is based on ndev_running flag that is updated before calling ndo_open/close, but if ndo is called in another place, as with suspend/resume, the counter is not changed, that breaks sus/resume. For common resource no difference which device is using it, does matter only device count. So, replace usage count function on var and inc and dec it in ndo_open/close. Signed-off-by:

Even though the port autoselection is enabled by default on AM79C970A, BNC/AUI port does not work because the link is always reported to be down. The link state reported by the chip belongs only to the TP port but the driver uses it regardless of the port used. The chip can't detect BNC/AUI link state. Disable port autoselection and use TP port by default to keep current behavior (link detection works on TP port, BNC/AUI port does not work). Implement ethtool autoneg, port and duplex configuration to allow using the BNC/AUI port. Report the TP link state only if the TP port is selected. When the port autoselection is enabled or AUI port is selected, report the link as always up. Move pcnet32_suspend() and pcnet32_clr_suspend() functions to avoid forward declarations. Signed-off-by:

Shannon Nelson says: ==================== sunvnet driver updates The sunvnet ldom virtual network driver was due for some updates and a bugfix or two. These patches address a few items left over from last year's make-over. v2: - changed memory barrier fix to use smp_wmb - put NETIF_F_SG back into the advertised ldmvsw hw_features v3: - the sunvnet_common module doesn't need module_init or _exit v4: - dropped the statistics patch - fixed up "default" tag for SUNVNET_COMMON ==================== Signed-off-by: -
Shannon Nelson authored
The ldmvsw driver is specifically for supporting the ldom virtual networking by running in the primary ldom and using the LDC to connect the remaining ldoms to the outside world via a bridge. With TSO and GSO supported while connected the bridge, things tend to misbehave as seen in our case by delayed packets, enough to begin triggering retransmits and affecting overall throughput. By turning off advertised support for TSO and GSO we restore stable traffic flow through the bridge. Orabug: 23293104 Signed-off-by:
