[ Upstream commit aa46dffff4 ]
We call bnxt_ulp_stop() to notify the RDMA driver that some error or
imminent reset is about to happen. After that we always call
some variants of bnxt_close().
In the next patch, we will integrate the recently added error
recovery with the RDMA driver. In response to ulp_stop, the
RDMA driver may free MSIX vectors and that will also trigger
bnxt_close(). To avoid bnxt_close() from being called twice,
we set a new flag after ulp_stop is called. If the RDMA driver
frees MSIX vectors while the new flag is set, we will not call
bnxt_close(), knowing that it will happen in due course.
With this change, we must make sure that the bnxt_close() call
after ulp_stop will reset IRQ. Modify bnxt_reset_task()
accordingly if we call ulp_stop.

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.
