====================
Add configuration parameters support
Add configuration parameters setting through devlink.
Each device registers supported configuration parameters table.
Each parameter can be either generic or driver specific.
The user can retrieve data on these parameters by "devlink param show"
command and can set new value to a parameter by "devlink param set"
command.
The parameters can be set in different configuration modes:
runtime - set while driver is running, no reset required.
driverinit - applied while driver initializes, requires restart
driver by devlink reload command.
permanent - written to device's non-volatile memory, hard reset required.
The patches at the end of the patchset introduce few params that are using
the introduced infrastructure on mlx4 and bnxt.
Command examples and output:
pci/0000:81:00.0:
name internal_error_reset type generic
values:
cmode runtime value true
cmode driverinit value true
name max_macs type generic
values:
cmode driverinit value 128
name enable_64b_cqe_eqe type driver-specific
values:
cmode driverinit value true
name enable_4k_uar type driver-specific
values:
cmode driverinit value false
pci/0000:81:00.0:
name internal_error_reset type generic
values:
cmode runtime value false
cmode driverinit value true

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
