When enabled for both SCSI and NVME support, and connected pt2pt to a SCSI only target, the driver nodelist entry for the remote port is left in PRLI_ISSUE state and no SCSI LUNs are discovered. Works fine if only configured for SCSI support. Error was due to some of the prli points still reflecting the need to send only 1 PRLI. On a lot of fabric configs, targets were NVME only, which meant the fabric-reported protocol attributes were only telling the driver one protocol or the other. Thus things worked fine. With pt2pt, the driver must send a PRLI for both protocols as there are no hints on what the target supports. Thus pt2pt targets were hitting the multiple PRLI issues. Complete the dual PRLI support. Track explicitly whether scsi (fcp) or nvme prli's have been sent. Accurately track protocol support detected on each node as reported by the fabric or probed by PRLI traffic.

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.
