Support create_mr and destroy_mr verbs. Creating ib_mr may be done for either ib_mr that will register regular page lists like alloc_fast_reg_mr routine, or indirect ib_mrs that can register other (pre-registered) ib_mrs in an indirect manner. In addition user may request signature enable, that will mean that the created ib_mr may be attached with signature attributes (BSF, PSVs). Currently we only allow direct/indirect registration modes.

Currently Connect-IB does not support blocking multicast loopback, so don't set IB_DEVICE_BLOCK_MULTICAST_LOOPBACK in the device caps. Reported by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: NEli Cohen <eli@mellanox.com> Signed-off-by: NRoland Dreier <roland@purestorage.com>

Commit c1be5232 ("Fix micro UAR allocator") broke binary compatibility between libmlx5 and mlx5_ib since it defines a different value to the number of micro UARs per page, leading to wrong calculation in libmlx5. This patch defines struct mlx5_ib_alloc_ucontext_req_v2 as an extension to struct mlx5_ib_alloc_ucontext_req. The extended size is determined in mlx5_ib_alloc_ucontext() and in case of old library we use uuarn 0 which works fine -- this is acheived due to create_user_qp() falling back from high to medium then to low class where low class will return 0. For new libraries we use the more sophisticated allocation algorithm.

The micro UAR (uuar) allocator had a bug which resulted from the fact that in each UAR we only have two micro UARs avaialable, those at index 0 and 1. This patch defines iterators to aid in traversing the list of available micro UARs when allocating a uuar. In addition, change the logic in create_user_qp() so that if high class allocation fails (high class means lower latency), we revert to medium class and not to the low class.

Use asynchronous commands to execute up to eight concurrent create MR commands. This is to fill memory caches faster so we keep consuming from there. Also, increase timeout for shrinking caches to five minutes. Signed-off-by: NEli Cohen <eli@mellanox.com> Signed-off-by: NRoland Dreier <roland@purestorage.com>

It's helpful for a driver to put the pci slot name in its interrupt names, so /proc/interrupts will show the pci slot of the device. Signed-off-by: NSagi Grimberg <sagig@mellanox.com> Signed-off-by: NEli Cohen <eli@mellanox.com> Signed-off-by: NRoland Dreier <roland@purestorage.com>

The driver is comprised of two kernel modules: mlx5_ib and mlx5_core. This partitioning resembles what we have for mlx4, except that mlx5_ib is the pci device driver and not mlx5_core. mlx5_core is essentially a library that provides general functionality that is intended to be used by other Mellanox devices that will be introduced in the future. mlx5_ib has a similar role as any hardware device under drivers/infiniband/hw.
