In the commit referenced below, a check was added to devlink_lib that
asserts the existence of a devlink device referenced by $DEVLINK_DEV.
Unfortunately, several netdevsim tests point DEVLINK_DEV at a device that
does not exist at the time that devlink_lib is sourced. Thus these tests
spuriously fail.
Fix this by introducing an override. By setting DEVLINK_DEV to an empty
string, the user declares their intention to handle DEVLINK_DEV management
on their own.
In all netdevsim tests that use devlink_lib and set DEVLINK_DEV, set
instead an empty DEVLINK_DEV just before sourcing devlink_lib, and set it
to the correct value right afterwards.

Add test to check fib notifications behavior.
The test checks route addition, route deletion and route replacement for
both IPv4 and IPv6.
When fib_notify_on_flag_change=0, expect single notification for route
addition/deletion/replacement.
When fib_notify_on_flag_change=1, expect:
- two notification for route addition/replacement, first without RTM_F_TRAP
and second with RTM_F_TRAP.
- single notification for route deletion.

The devlink interface recently gained support for a new "overwrite mask"
parameter that allows specifying how various sub-sections of a flash
component are modified when updating.
Add support for this to netdevsim, to enable easily testing the
interface. Make the allowed overwrite mask values controllable via
a debugfs parameter. This enables testing a flow where the driver
rejects an unsupportable overwrite mask.

The devlink core recently gained support for checking whether the driver
supports a flash_update parameter, via `supported_flash_update_params`.
However, parameters are specified as function arguments. Adding a new
parameter still requires modifying the signature of the .flash_update
callback in all drivers.
Convert the .flash_update function to take a new `struct
devlink_flash_update_params` instead. By using this structure, and the
`supported_flash_update_params` bit field, a new parameter to
flash_update can be added without requiring modification to existing
drivers.
As before, all parameters except file_name will require driver opt-in.
Because file_name is a necessary field to for the flash_update to make
sense, no "SUPPORTED" bitflag is provided and it is always considered
valid. All future additional parameters will require a new bit in the
supported_flash_update_params bitfield.
