A mirror of the official Linux kernel repository just in case
fc8b086d9d
When the commit adding ntb_default_port_number() and
ntb_default_peer_port_number() entered the kernel there was no
users of it so it was impossible to tell what the API needed.
When a user finally landed a year later (ntb_pingpong) there were
more NTB topologies were created and no consideration was considered
to how other drivers had changed.
Now that there is a user it can be fixed to provide a sensible default
for the legacy drivers that do not implement ntb_{peer_}port_number().
Seeing ntb_pingpong doesn't check error codes returning EINVAL was also
not sensible.
Patches for ntb_pingpong and ntb_perf follow (which are broken
otherwise) to support hardware that doesn't have port numbers. This is
important not only to not break support with existing drivers but for
the cross link topology which, due to its perfect symmetry, cannot
assign unique port numbers to each side.

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.
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.
