2016-03-10net: dsa: Fix cleanup resources upon module removalNeil Armstrong
The initial commit badly merged into the dsa_resume method instead of the dsa_remove_dst method. As consequence, the dst->master_netdev->dsa_ptr is not set to NULL on removal and re-bind of the dsa device fails with error -17.

Rajesh Borundia says: ==================== qlcnic fixes This series adds following fixes. o While processing mailbox if driver gets a spurious mailbox interrupt it leads into premature completion of a next mailbox request. Added a guard against this by checking current state of mailbox and ignored spurious interrupt. Added a stats counter to record this condition. v2: o Added patch that removes usage of atomic_t as we are not implemeting atomicity by using atomic_t value. ==================== Signed-off-by: David S.

2016-03-10qlcnic: Fix mailbox completion handling during spurious interruptRajesh Borundia
o While the driver is in the middle of a MB completion processing and it receives a spurious MB interrupt, it is mistaken as a good MB completion interrupt leading to premature completion of the next MB request. Fix the driver to guard against this by checking the current state of MB processing and ignore the spurious interrupt. Also added a stats counter to record this condition.

Hariprasad Shenai says: ==================== cxgb4vf: Interrupt and queue configuration changes This series fixes some issues and some changes in the queue and interrupt configuration for cxgb4vf driver. We need to enable interrupts before we register our network device, so that we don't loose link up interrupts. Allocate rx queues based on interrupt type. Set number of tx/rx queues in probe function only. Also adds check for some invalid configurations. This patch series has been created against net-next tree and includes patches on cxgb4vf driver. We have included all the maintainers of respective drivers. Kindly review the change and let us know in case of any review comments. ==================== Signed-off-by: David S.

2016-03-10cxgb4vf: Configure queue based on resource and interrupt typeHariprasad Shenai
The Queue Set Configuration code was always reserving room for a Forwarded interrupt Queue even in the cases where we weren't using it. Figure out how many Ports and Queue Sets we can support. This depends on knowing our Virtual Function Resources and may be called a second time if we fall back from MSI-X to MSI Interrupt Mode. This change fixes that problem.

2016-03-10cxgb4vf: Enable interrupts before we register our network devicesHariprasad Shenai
This avoids a race condition where a system that has network devices set up to be automatically configured and we get the first Port Link Status message from the firmware on the Asynchronous Firmware Event Queue before we've enabled interrupts. If that happens, we end up losing the interrupt and never realizing that the links has actually come up. Signed-off-by: Hariprasad Shenai <hariprasad@chelsio.com> Signed-off-by: David S.

2016-03-10sh_eth: advance 'rxdesc' later in sh_eth_ring_format()Sergei Shtylyov
Iff dma_map_single() fails, 'rxdesc' should point to the last filled RX descriptor, so that it can be marked as the last one, however the driver would have already advanced it by that time. In order to fix that, only fill an RX descriptor once all the data for it is ready. Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> Signed-off-by: David S.

2016-03-10kcm: mark helper functions inlineArnd Bergmann
The stub helper functions for the newly added kcm_proc_init/exit interfaces are defined as 'static' in a header file, which leads to build warnings for each file that includes them without calling them: include/net/kcm.h:183:12: error: 'kcm_proc_init' defined but not used [-Werror=unused-function] include/net/kcm.h:184:13: error: 'kcm_proc_exit' defined but not used [-Werror=unused-function] This marks the two functions as 'static inline' instead, which avoids the warnings and is obviously what was meant here.
