devlink: rename and expand devlink-trap-netdevsim.rst

Rename the trap-specific netdevimsim.rst file, and expand it to include
documentation of all the devlink features currently implemented by the
netdevsim driver code.

netdevsim devlink support
=========================
This document describes the ``devlink`` features supported by the
``netdevsim`` device driver.
Parameters
==========
.. list-table:: Generic parameters implemented
* - Name
- Mode
* - ``max_macs``
- driverinit
The ``netdevsim`` driver also implements the following driver-specific
parameters.
.. list-table:: Driver-specific parameters implemented
:widths: 5 5 5 85
* - Name
- Type
- Mode
- Description
* - ``test1``
- Boolean
- driverinit
- Test parameter used to show how a driver-specific devlink parameter
can be implemented.
The ``netdevsim`` driver supports reloading via ``DEVLINK_CMD_RELOAD``
Regions
=======
The ``netdevsim`` driver exposes a ``dummy`` region as an example of how the
devlink-region interfaces work. A snapshot is taken whenever the
``take_snapshot`` debugfs file is written to.
Resources
=========
The ``netdevsim`` driver exposes resources to control the number of FIB
entries and FIB rule entries that the driver will allow.
.. code:: shell
$ devlink resource set netdevsim/netdevsim0 path /IPv4/fib size 96
$ devlink resource set netdevsim/netdevsim0 path /IPv4/fib-rules size 16
$ devlink resource set netdevsim/netdevsim0 path /IPv6/fib size 64
$ devlink resource set netdevsim/netdevsim0 path /IPv6/fib-rules size 16
$ devlink dev reload netdevsim/netdevsim0
