Do not rely on vendor version field of the CSPs to determine if we are in a FA-PWWN environment. Instead, use the following procedure: First, during HBA initialization, driver does a READ_CONFIG to determine if FA-PWWN is configured on the HBA. A LPFC_FAWWPN_CONFIG hba_flag is set accordingly. Next, when the link comes up before the driver gets a link up event, the firmware logs into the fabric with FA-PWWN. If the fabric port does not support FA-PWWN, the driver will get a Misconfigured FA-WWN async event before the link up. A LPFC_FAWWPN_FABRIC hba_flag will be set accordingly. Finally, if the fabric supports FA-PWWN, the firmware will replace its CSPs WWN with the Fabric Assigned ones. Then after link up, the driver will retrieve the Fabric Assigned WWN when it does a READ_SPARAM mbox command.

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.
