- The biggest change is core API extensions and mlx5 low-level driver
support for handling DIF/DIX-style protection information, and the
addition of PI support to the iSER initiator. Target support will be
arriving shortly through the SCSI target tree.
- A nice simplification to the "umem" memory pinning library now that
we have chained sg lists. Kudos to Yishai Hadas for realizing our
code didn't have to be so crazy.
- Another nice simplification to the sg wrappers used by qib, ipath and
ehca to handle their mapping of memory to adapter.
- The usual batch of fixes to bugs found by static checkers etc. from
intrepid people like Dan Carpenter and Yann Droneaud.
- A large batch of cxgb4, ocrdma, qib driver updates.
