Ray Jui b35e732134 bnxt_en: Need to unconditionally shut down RoCE in bnxt_shutdown 
[ Upstream commit a7f3f939dd ]

The current 'bnxt_shutdown' implementation only invokes
'bnxt_ulp_shutdown' to shut down RoCE in the case when the system is in
the path of power off (SYSTEM_POWER_OFF). While this may work in most
cases, it does not work in the smart NIC case, when Linux 'reboot'
command is initiated from the Linux that runs on the ARM cores of the
NIC card. In this particular case, Linux 'reboot' results in a system
'L3' level reset where the entire ARM and associated subsystems are
being reset, but at the same time, Nitro core is being kept in sane state
(to allow external PCIe connected servers to continue to work). Without
properly shutting down RoCE and freeing all associated resources, it
results in the ARM core to hang immediately after the 'reboot'

By always invoking 'bnxt_ulp_shutdown' in 'bnxt_shutdown', it fixes the
above issue

Fixes: 0efd2fc65c ("bnxt_en: Add a callback to inform RDMA driver during PCI shutdown.")

README 

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.
