We've seen a few devices that return different controller id's to the Fabric Connect command vs the Identify(controller) command. It's currently hard to identify this failure by existing error messages. It comes across as a (re)connect attempt in the transport that fails with a -22 (-EINVAL) status. The issue is compounded by older kernels not having the controller id check or had the identify command overwrite the fabrics controller id value before it checked. Both resulted in cases where the devices appeared fine until more recent kernels. Clarify the reject by adding an error message on controller id mismatches.

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.
