According to FC-LS-3 (Fibre Channel Link Services) 6.3.2.4 "N_Port Login - No Fabric present", if both parties in the point-to-point connection know N_Port_Names of each other, Nx_Port with the highest N_Port_name shall transmit PLOGI. The specification sets no restrictions on the port role that should send PLOGI. However, FCP-4 (Fibre Channel Protocol for SCSI, Fourth Version) 6.2 "Overview of Process Login and Process Logout", instructs that in point-to-point topology, initiator shall send explicit PRLI ELS. The change fixes stuck P2P login, when target WWPN is higher than initiator WWPN.

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.
