In cases of remote-port-side cable pull/replug, there happens to be a target that upon replug will send the port a PLOGI, a PRLI, and a LOGO. When this sequence is received by the driver, the PLOGI accepted and a GFT_ID is issued to find the protocol support for the remote port. While the GFT_ID is outstanding, a LOGO is received. The driver logs the remote port out and unregisters the RPI and schedules a new PLOGI transmission. However, the GFT_ID was not terminated. When it completed, the driver attempted to transition the remote port to PRLI transmission, which cancels the PLOGI scheduling. The PRLI transmit attempt is rejected by the adapter as the remote port is not logged in. No retry is attempted as it's expected the logout is noted and the supposedly scheduled PLOGI should address the state. As there is no PLOGI, the remote port does not get re-discovered. Fix by aborting the outstanding GFT_ID if the related remote port is logged out. Ensure a PRLI transmit attempt only occurs if the remote port is logging in. This avoids the incorrect attempt while logged out. Signed-off-by: Dick Kennedy <dick.kennedy@broadcom.com> Signed-off-by: James Smart <jsmart2021@gmail.com> Signed-off-by: Martin K.

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.
