Eli Cohen 1a4c3a3dc5 IB/mlx5: Don't set "block multicast loopback" capability
Currently Connect-IB does not support blocking multicast loopback, so
don't set IB_DEVICE_BLOCK_MULTICAST_LOOPBACK in the device caps.

Eli Cohen 78c0f98cc9 IB/mlx5: Fix binary compatibility with libmlx5
Commit c1be5232d2 ("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.

Eli Cohen c1be5232d2 IB/mlx5: Fix micro UAR allocator
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.

Eli Cohen 746b5583c1 IB/mlx5: Multithreaded create MR
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.

Sagi Grimberg ada9f5d007 IB/mlx5: Fix eq names to display nicely in /proc/interrupts
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.

Eli Cohen a0c84c326f IB/mlx5: Avoid async events on invalid port number
On a single ported Connect-IB, its possible for the firmware to issue
events on the non-existing 2nd port.  Make sure to ignore events
generated for such ports.

Dan Carpenter 92b0ca7cb1 IB/mlx5: Fix stack info leak in mlx5_ib_alloc_ucontext()
We don't set "resp.reserved".  Since it's at the end of the struct
that means we don't have to copy it to the user.

Eli Cohen e126ba97db mlx5: Add driver for Mellanox Connect-IB adapters
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.
