The firmware reset and loading policies can be controlled with the combination of three hwinfo keys, 'abi_drv_reset', 'abi_drv_load_ifc' and 'app_fw_from_flash'. 'app_fw_from_flash' defines which firmware should take precedence, 'Disk', 'Flash' or the 'Preferred' firmware. When 'Preferred' is selected, the management firmware makes the decision on which firmware will be loaded by comparing versions of the flash firmware and the host supplied firmware. 'abi_drv_reset' defines when the driver should reset the firmware when the driver is probed, either 'Disk' if firmware was found on disk, 'Always' reset or 'Never' reset. Note that the device is always reset on driver unload if firmware was loaded when the driver was probed. 'abi_drv_load_ifc' defines a list of PF devices allowed to load FW on the device. Furthermore, we limit the cases to where the driver will unload firmware again when the driver is removed to only when firmware was loaded by the driver and only if this particular device was the only one that could have loaded firmware. This is needed to avoid firmware being removed while in use on multi-host platforms.

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.
