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.

b125a54bfd IB/mlx5: Fix send work queue size calculation
1. Make sure wqe_cnt does not exceed the limit published by firmware.

2. There is no requirement that the number of outstanding work
   requests will be a power of two. Remove the ilog2 in the
   calculation of sq.max_post to fix that.

3. Add case for IB_QPT_XRC_TGT in sq_overhead and return 0 as XRC
   target QPs do not have a send queue.

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.
