[ Upstream commit 5311598f7f3293683cdc761df71ae3469327332c ]
After successful PCIe AER recovery, FW will reset all resource
reservations. If it is IF_UP, the driver will call bnxt_open() and
all resources will be reserved again. It it is IF_DOWN, we should
call bnxt_reserve_rings() so that we can reserve resources including
RoCE resources to allow RoCE to resume after AER. Without this
patch, RoCE fails to resume in this IF_DOWN scenario.
Later, if it becomes IF_UP, bnxt_open() will see that resources have
been reserved and will not reserve again.
Fixes: fb1e6e562b ("bnxt_en: Fix AER 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.
