The spec was fairly confusing about how multi-part transmit messages worked, so the original implementation only added support for two part messages. But after talking about it with others and finding something I missed, I think it makes more sense. The spec mentions smbus command 8 in a table at the end of the section on SSIF support as the end transaction. If that works, then all is good and as it should be. However, some implementations seem to use a middle transaction <32 bytes tomark the end because of the confusion in the spec, even though that is an SMBus violation if the number of bytes is zero. So this change adds some tests, if command=8 works, it uses that, otherwise if an empty end transaction works, it uses a middle transaction <32 bytes to mark the end. If neither works, then it limits the size to 63 bytes as it is now.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
