Michael Chan e8c8d2319b bnxt_en: Improve stats context resource accounting with RDMA driver loaded.
commit 869c4d5eb1e6fbda66aa790c48bdb946d71494a0 upstream.

The function bnxt_get_ulp_stat_ctxs() does not count the stats contexts
used by the RDMA driver correctly when the RDMA driver is freeing the
MSIX vectors.  It assumes that if the RDMA driver is registered, the
additional stats contexts will be needed.  This is not true when the
RDMA driver is about to unregister and frees the MSIX vectors.

This slight error leads to over accouting of the stats contexts needed
after the RDMA driver has unloaded.  This will cause some firmware
warning and error messages in dmesg during subsequent config. changes
or ifdown/ifup.

Fix it by properly accouting for extra stats contexts only if the
RDMA driver is registered and MSIX vectors have been successfully
requested.

README

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.
