The current logic that calls pci_disable_device() in __bnxt_close_nic()
during firmware reset is flawed. If firmware is still alive, we're
disabling the device too early, causing some firmware commands to
not reach the firmware.
Fix it by moving the logic to bnxt_reset_close(). If firmware is
in fatal condition, we call pci_disable_device() before we free
any of the rings to prevent DMA corruption of the freed rings. If
firmware is still alive, we call pci_disable_device() after the
last firmware message has been sent.

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.
