In the event flow, we currently pass only a port number in the void *data argument. Rather than pass a pointer to the event handlers, we should use an "unsigned long" parameter, and pass the port number value directly. In the future, if necessary for some events, we can use the unsigned long parameter to pass a pointer.

There were many places where parameters which should be u8/u16 were integer type. Additionally, in 2 places, a check for a non-null pointer was added before dereferencing the pointer (this is actually a bug fix).

In preparation for a new mlx5 device which is VPI (i.e., ports can be either IB or ETH), move the pci device functionality from mlx5_ib to mlx5_core. This involves the following changes: 1. Move mlx5_core_dev struct out of mlx5_ib_dev. mlx5_core_dev is now an independent structure maintained by mlx5_core. mlx5_ib_dev now has a pointer to that struct. This requires changing a lot of places where the core_dev struct was accessed via mlx5_ib_dev (now, this needs to be a pointer dereference). 2. All PCI initializations are now done in mlx5_core. Thus, it is now mlx5_core which does pci_register_device (and not mlx5_ib, as was previously). 3. mlx5_ib now registers itself with mlx5_core as an "interface" driver. This is very similar to the mechanism employed for the mlx4 (ConnectX) driver. Once the HCA is initialized (by mlx5_core), it invokes the interface drivers to do their initializations. 4. There is a new event handler which the core registers: mlx5_core_event(). This event handler invokes the event handlers registered by the interfaces.

This commit takes care of the generated signature error CQE generated by the HW (if happened). The underlying mlx5 driver will handle signature error completions and will mark the relevant memory region as dirty. Once the consumer gets the completion for the transaction, it must check for signature errors on signature memory region using a new lightweight verb ib_check_mr_status(). In case the user doesn't check for signature error (i.e. doesn't call ib_check_mr_status() with status check IB_MR_CHECK_SIG_STATUS), the memory region cannot be used for another signature operation (REG_SIG_MR work request will fail).

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.

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.

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.
