Currently, all adapters that cxlflash supports must have WWPN VPD keywords to complete configuration. This was required as cards with external FC ports needed to be programmed with WWPNs. Newer supported cards do not have an external FC interface and therefore do not require WWPN. To support backwards compatibility, these devices have included 'dummy' WWPN VPD with WWPN values of zero. This however places a dependency that all future cards have WWPN VPD, which may not always be the case. Allow for cards to not have WWPN, designating which cards are expected to have it in order to configure properly. Signed-off-by: Matthew R.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
