In order to read the firmware health status, we first need to determine the register location and then the register may need to be mapped. There are 2 code paths to do this. The first one is done early as a best effort attempt by the function bnxt_try_map_fw_health_reg(). The second one is done later in the function bnxt_map_fw_health_regs() after establishing communications with the firmware. We currently only set fw_health->status_reliable if we can successfully set up the health register in the first code path. Improve the scheme by setting the fw_health->status_reliable flag if either (or both) code paths can successfully set up the health register. This flag is relied upon during run-time when we need to check the health status. So this will make it work better. During ifdown, if the health register is mapped, we need to invalidate the health register mapping because a potential fw reset will reset the mapping. Similarly, we need to do the same after firmware reset during recovery. We'll remap it during ifup.

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.
