Failure in kmalloc memory allocations will throw a warning about it. Such warnings are not needed anymore, since in commit 0ef2f05c ("IB/mlx4: Use vmalloc for WR buffers when needed"), fallback mechanism from kmalloc() to __vmalloc() was added.

It was found that when a process was rapidly sending MADs other processes could be hung in their unregister calls. This would happen when process A was injecting packets fast enough that the single threaded workqueue was never exiting ib_mad_completion_handler. Therefore when process B called flush_workqueue via the unregister call it would hang until process A stopped sending MADs. The fix is to periodically reschedule ib_mad_completion_handler after processing a large number of completions. The number of completions chosen was decided based on the defaults for the recv queue size. However, it was kept fixed such that increasing those queue sizes would not adversely affect fairness in the future.

Add support of cross-channel functionality to mlx5 driver. This includes ability to ignore overrun for CQ which intended for cross-channel, export device capability and configure the QP to be sync master/slave queues. The cross-channel enabled QP supports combination of three possible properties: * WQE processing on the receive queue of this QP * WQE processing on the send queue of this QP * WQE are supported on the send queue Reviewed-by: Sagi Grimberg <sagig@mellanox.com> Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Doug Ledford <dledford@redhat.com>

The cross-channel feature allows to execute WQEs that involve synchronization of I/O operations’ on different QPs. This capability enables to program complex flows with a single function call, hereby significantly reducing overhead associated with I/O processing. Cross-channel operations support is indicated by HCA capability information. The queue pairs can be configured to work as a “sync master queue” or “sync slave queues”. The added flags are: 1. Device capability flag IB_DEVICE_CROSS_CHANNEL for the devices that can perform cross-channel operations. 2. CQ property flag IB_CQ_FLAGS_IGNORE_OVERRUN to disable CQ overrun check. This check is useless in cross-channel scenario. 3. QP property flags to indicate if queues are slave or master: * IB_QP_CREATE_MANAGED_SEND indicates that posted send work requests will not be executed immediately and requires enabling. * IB_QP_CREATE_MANAGED_RECV indicates that posted receive work requests will not be executed immediately and requires enabling. * IB_QP_CREATE_CROSS_CHANNEL declares the QP to work in cross-channel mode. If IB_QP_CREATE_MANAGED_SEND and IB_QP_CREATE_MANAGED_RECV are not provided, this QP will be sync master queue, else it will be sync slave.
