* ab8500_bm: Always send platform specific battery information via pdataLee Jones2012-12-117-32/+19
| | | | | | | | | | | | | | | | Currently the AB8500 battery management subsystem receives platform specific information via two different means depending on how the platform is booted. If DT is not enabled, a reference to a *_bm_data data structure containing each platform specific attribute is passed though platform_data. However, if DT is enabled, then platform_data is empty and the reference is gained though a DT specific probe function. There are two issues here 1) the same reference is being collected each time and 2) the DT way doesn't allow any provisions to select different platform specific attributes, which kind of defeats the object.

* ab8500_bm: Rename battery management platform data to something more logicalLee Jones2012-12-116-152/+152
| | | | | | | | | | | | | The platform specific battery management configuration data structure is currently called 'bat' short for 'battery'; however, it contains information for all components of the battery management group, rather than information pertaining to the battery itself - there are other structures for that. So, in keeping with its structure namesake 'abx500_bm_data', we rename it to 'bm' here. Using similar logic, we're also renaming 'bmdevs_of_probe' to the more device specific 'ab8500_bm_of_probe'.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a gianfar ethernet device is down prior to hibernating a system, it will no longer be present upon system restore. For example: ~# ifconfig eth0 down ~# echo disk > /sys/power/state <trigger a restore from hibernation> ~# ifconfig eth0 up SIOCSIFFLAGS: No such device This happens because the restore function bails out early upon finding devices that were not up at hibernation. In doing so, it never gets to the netif_device_attach call at the end of the restore function. Adding the netif_device_attach as done here also makes the gfar_restore code consistent with what is done in the gfar_resume code.

| * pkt_sched: enable QFQ to support TSO/GSOPaolo Valente2012-11-071-30/+79

This problem occurs with TSO/GSO even if the max packet size is set to the MTU, and is, e.g., the cause of the failure reported in [1]. Two patches have been proposed to solve this problem in [2], one of them is a preliminary version of this patch. This patch addresses the above issues by: 1) setting QFQ parameters to proper values for supporting TSO/GSO (in particular, setting the maximum possible packet size to 64KB), 2) automatically increasing the max packet size for a class, lmax, when a packet with a larger size than the current value of lmax arrives. The drawback of the first point is that the maximum weight for a class is now limited to 4096, which is equal to 1/16 of the maximum weight sum. Finally, this patch also forcibly caps the timestamps of a class if they are too high to be stored in the bucket list. This capping, taken from QFQ+ [3], handles the unfrequent case described in the comment to the function slot_insert.

| * net: inet_diag -- Return error code if protocol handler is missedCyrill Gorcunov2012-11-041-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We've observed that in case if UDP diag module is not supported in kernel the netlink returns NLMSG_DONE without notifying a caller that handler is missed. This patch makes __inet_diag_dump to return error code instead. So as example it become possible to detect such situation and handle it gracefully on userspace level.

| * smsc95xx: fix tx checksum offload for big endianSteve Glendinning2012-11-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | f7b2927 introduced tx checksum offload support for smsc95xx, and enabled it by default. This feature doesn't take endianness into account, so causes most tx to fail on those platforms. This patch fixes the problem fully by adding the missing conversion. An alternate workaround is to disable TX checksum offload on those platforms. The cpu impact of this feature is very low.

| * rtnetlink: Use nlmsg type RTM_NEWNEIGH from dflt fdb dumpJohn Fastabend2012-11-031-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change the dflt fdb dump handler to use RTM_NEWNEIGH to be compatible with bridge dump routines. The dump reply from the network driver handlers should match the reply from bridge handler. The fact they were not in the ixgbe case was effectively a bug. This patch resolves it. Applications that were not checking the nlmsg type will continue to work. And now applications that do check the type will work as expected.

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch updates the adjfreq callback description to include a note that the delta in ppb is always relative to the base frequency, and not to the current frequency of the hardware clock.
