2018-01-09wcn36xx: fix incorrect assignment to msg_body.min_ch_timeColin Ian King
The second assignment to msg_body.min_ch_time is incorrect, it should actually be to msg_body.max_ch_time. Thanks to Bjorn Andersson for identifying the correct way to fix this as my original fix was incorrect.

2018-01-09wil6210: prevent parallel suspend and dump collectionMaya Erez
Suspend and crash dump operations can happen simultaneously in case there is a FW assert during the suspend procedure or when SSR calls all the devices crashdump callbacks.

2017-12-27ath10k: add memory dump support for QCA6174/QCA9377Alan Liu
Add memory dump to the firmware crash data file which is provided to user space via devcoredump interface. This makes it easier for firmware engineers to debug firmware crashes. Due to increased memory consumption the memory dump is disabled by default. To enable it make sure that bit 3 is set in coredump_mask module parameter: modprobe ath10k_core coredump_mask=0xffffffff When RAMDUMP is enabled a buffer for the dump is allocated with vmalloc during device probe. The actual memory layout is different in hardware versions and the layouts are defined in coredump.c. The memory is split to regions and, to get even finegrained control of what to copy, the region can split to smaller sections as not all registers are readable (which could cause the whole system to stall).

2017-12-27ath10k: add coredump_mask module parameterKalle Valo

2017-12-19Merge branch 'nfp-flower-add-Geneve-tunnel-support'David S. Miller
Simon Horman says: ==================== nfp: flower: add Geneve tunnel support John Hurley says: This patchset adds support for offloading the encap and decap of Geneve tunnels to the NFP. In both cases, specifying well known port 6081 is a requirement for rule offload. Geneve firmware support has been recently added, so the patchset includes the reading of a fw symbol that defines a bitmap of newly supported features. Geneve will only be offloaded if the fw supports it. The new symbol is added in fw r5646. Geneve option fields are not supported as either a match or an action due there current exclussion from TC flower. Because Geneve (as both a match and action) behaves the same as other udp tunnels such as VXLAN, generic functions are created that handle both Geneve and VXLAN. It is anticapated that these functions will be modified to support options in future patches. The removal of an unused variable 'tun_dst_mask' is included as a separate patch here. This does not affect functionality. Also included are modifications to the test framework to check that the new encap and decap features are functioning correctly. ==================== Signed-off-by: David S.

Rather than adding new Geneve blocks, move the vxlan code to generic ipv4 udp tunnel structs and use these for both vxlan and Geneve. Matches are only supported when specifically mentioning well known port 6081. Geneve tunnel options are not yet included in the match.

The tunnel dest IP is required for separate offload to the NFP. It is already verified that a dest IP must be present and must be an exact match in the flower rule. Therefore, we can just extract the IP from the generated offload rule and remove the unused mask variable. The function is then no longer required to return the IP separately.
