This test is missing a whole bunch of checks for interface
renaming and one ifup. Presumably it was only used on a system
with renaming disabled and NetworkManager running.

netdevsim tests aren't very well integrated with kselftest,
which has its advantages and disadvantages. But regardless

The file name used in flash test was "dummy" because at the time test
was written, drivers were responsible for file request and as netdevsim
didn't do that, name was unused. However, the file load request is
now done in devlink code and therefore the file has to exist.
Use first random file from /lib/firmware for this purpose.

When devlink instance is put into network namespace and that network
namespace gets deleted, devlink instance is moved back into init_ns.
This is done as a part of cleanup_net() routine. Since cleanup_net()
is called asynchronously from workqueue, there is no guarantee that
the devlink instance move is done after "ip netns del" returns.
So fix this race by making sure that the devlink instance is present
before any other operation.

$number + > bash means redirect FD $number, e.g. commonly

write the number 8192 to a file, this results in:
./devlink.sh: line 499: 8192: Bad file descriptor
Oddly the test also papers over this issue by checking

Add IPv4 and IPv6 test cases that ensure that we are not leaking a
reference on the nexthop device when we are unable to delete its
associated route.
Without the fix in a previous patch ("netdevsim: fib: Fix reference

waiting for the reference to be released from the dummy device [1][2].

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.

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.

The variable is used by log_test() to check if the test case completely

```
...
TEST: Trap group statistics [ OK ]
TEST: Trap policer [FAIL]
Policer drop counter was not incremented
TEST: Trap policer binding [FAIL]
Policer drop counter was not incremented
```
Failure of trap_policer_test() caused trap_policer_bind_test() to fail
as well.
