If a remote port is removed and remains removed for devloss_tmo, if an RSCN is subsequently received indicating the presence of the remte port, the driver does not login to and rediscovery the remote port. Currently, in order to for a port to be rediscovered post an RSCN, the node state must be NPR to reflect not logged in. When devloss expires, the node state is marked UNUSED. When an RSCN occurs, the nodes referenced by the RSCN will have a NPR_2B_DISC flag set, but the re-login will only be attempted if the node is in NPR_NODE state. Thus the node is skipped over. Fix by recognizing the NPR_2B_DISC and UNUSED and transition the node back to NPR state to allow the re-login to take place.

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.
