When the WriteObject mailbox response has change_status set to is 0x2 (Firmware Reset) or 0x04 (Port Migration Reset), the CSF field should also be checked to see if a fw reset is sufficient to enable all new features in the updated firmware image. If not, a fw reset would start the new firmware, but with a feature level equal to existing firmware. To enable the new features, a chip reset/pci slot reset would be required. Check the CSF bit when change_status is 0x2 or 0x4 to know whether to perform a pci bus reset or fw reset.

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.
