Add support for a common iWARP query port function, the new function includes a common code that is used by the iWARP devices to update the port attributes like max_mtu, active_mtu, state, and phys_state, the function also includes a call for the driver-specific query_port callback to query the device-specific port attributes.

Admin queue error prints should never happen unless something wrong happened to the device. However, in the unfortunate case that it does, we should take extra care not to flood the log with error messages. Reviewed-by:

Chuck Lever authored
Send and Receive completion is handled on a single CPU selected at the time each Completion Queue is allocated. Typically this is when an initiator instantiates an RDMA transport, or when a target accepts an RDMA connection. Some ULPs cannot open a connection per CPU to spread completion workload across available CPUs and MSI vectors. For such ULPs, provide an API that allows the RDMA core to select a completion vector based on the device's complement of available comp_vecs. ULPs that invoke ib_alloc_cq() with only comp_vector 0 are converted to use the new API so that their completion workloads interfere less with each other. Suggested-by:

We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // <smpl> @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // </smpl> While we're here, remove braces on if statements that only have one statement (manually).

Now that IB core supports RDMA device binding with specific net namespace, enable IB core to accept netlink commands in non init_net namespaces. This is done by having per net namespace netlink socket. At present only netlink device handling client RDMA_NL_NLDEV supports device handling in multiple net namespaces. Hence do not accept netlink messages for other clients in non init_net net namespaces. Link: https://lore.kernel.org/r/20190723070205.6247-1-leon@kernel.orgSigned-off-by:

The mlx4 WQ is implemented with HW QP without special HW object. Current implementation which tried to reuse the code did it with common QP creation flows. Such decision caused to the absence of mlx4_ib_wq struct, which is needed to ensure proper allocation of ib_wq inside of IB/core. Separate create_qp_common() to pure QP flow and to create_rq() for RWQ. Link: https://lore.kernel.org/r/20190704130936.8705-2-leon@kernel.orgSigned-off-by:
