61f51b7b20 i40iw: Set 128B as the only supported RQ WQE size
RQ WQE size other than 128B is not supported.  Correct
RQ size calculation to use 128B only.

Since this breaks ABI, add additional code to
provide compatibility with v4 user provider, libi40iw.

0fc2dc5889 i40iw: Add Quality of Service support
Add support for QoS on QPs. Upon device initialization,
a map is created from user priority to queue set
handles. On QP creation, use ToS to look up the queue
set handle for use with the QP.

34abf9ed73 i40iw: Replace the obsolete crypto hash interface with shash
This patch replaces the obsolete crypto hash interface with shash
and resolves a build failure after merge of the rdma tree
which is caused by the removal of crypto hash interface

Removing CRYPTO_ALG_ASYNC from crypto_alloc_shash(),
because it is by definition sync only
