Currently we use PORTn_OFFSET to locate PORT DFLs, and PORT DFLs are not connected FME DFL. But for some cases (e.g. Intel Open FPGA Stack device), PORT DFLs are connected to FME DFL directly, so we don't need to search PORT DFLs via PORTn_OFFSET again. If BAR value of PORTn_OFFSET is 0x7 (FME_PORT_OFST_BAR_SKIP) then driver will skip searching the DFL for that port. If BAR value is invalid, return -EINVAL.

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.
