This patch set contributes version 6 of the SoftiWarp
driver, as originally introduced to the list Oct 6th, 2017.
SoftiWarp (siw) implements the iWarp RDMA protocol over
kernel TCP sockets. The driver integrates with the
linux-rdma framework.


In response to the various helpful feedback, I fixed
the following issues:

1. Only the 'SPDX-License-Identifier' is present, the
   old explicit license text got removed.

2. The clang tool was applied to remove horizontal white
   spaces consistently and re-format the code.

3. Many smaller functional and style issues, as discussed
   at the mailing list, got fixed.

4. The driver was rebased to branch 'for-next' of
   git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git

I maintain a snapshot of the current code at
https://github.com/zrlio/softiwarp-for-linux-rdma.git
within branch 'siw-for-rdma-next-v6'.

The matching siw user library is maintained at
https://github.com/zrlio/softiwarp-user-for-linux-rdma.git.
The relevant branch name is 'siw-for-rdma-next'.

As always, I'd highly appreciate your code review. Thanks
very much for your time!

Bernard
