Michael Chan 2806757291 bnxt_en: Fix RDMA driver failure with SRIOV after firmware reset. 
[ Upstream commit 12de2eadf8 ]

bnxt_ulp_start() needs to be called before SRIOV is re-enabled after
firmware reset.  Re-enabling SRIOV may consume all the resources and
may cause the RDMA driver to fail to get MSIX and other resources.
Fix it by calling bnxt_ulp_start() first before calling
bnxt_reenable_sriov().

We re-arrange the logic so that we call bnxt_ulp_start() and
bnxt_reenable_sriov() in proper sequence in bnxt_fw_reset_task() and
bnxt_open().  The former is the normal coordinated firmware reset sequence
and the latter is firmware reset while the function is down.  This new
logic is now more straight forward and will now fix both scenarios.

Fixes: f3a6d206c2 ("bnxt_en: Call bnxt_ulp_stop()/bnxt_ulp_start() during error recovery.")

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.
