9ee53e3753 selftests: netdevsim: Test route offload failure notifications
Add cases to verify that when debugfs variable "fail_route_offload" is
set, notification with "rt_offload_failed" flag is received.

Extend the existing cases to verify that when sysctl
"fib_notify_on_flag_change" is set to 2, the kernel emits notifications
only for failed route installation.

$ ./fib_notifications.sh
TEST: IPv4 route addition				[ OK ]
TEST: IPv4 route deletion				[ OK ]
TEST: IPv4 route replacement				[ OK ]
TEST: IPv4 route offload failed				[ OK ]
TEST: IPv6 route addition				[ OK ]
TEST: IPv6 route deletion				[ OK ]
TEST: IPv6 route replacement				[ OK ]
TEST: IPv6 route offload failed				[ OK ]

f72e2f48c7 net: selftests: Add lanes setting test
Test that setting lanes parameter is working.

Set max speed and max lanes in the list of advertised link modes,
and then try to set max speed with the lanes below max lanes if exists
in the list.

And then, test that setting number of lanes larger than max lanes fails.

Do the above for both autoneg on and off.

$ ./ethtool_lanes.sh

TEST: 4 lanes is autonegotiated                                     [ OK ]
TEST: Lanes number larger than max width is not set                 [ OK ]
TEST: Autoneg off, 4 lanes detected during force mode               [ OK ]

19d36d2971 selftests: netdevsim: Add fib_notifications test
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.

$ ./fib_notifications.sh

The test was setting the headroom size of the wrong port. This was not

8cd6b020b6 selftests: ocelot: add some example VCAP IS1, IS2 and ES0 tc offloads
Provide an example script which can be used as a skeleton for offloading
TCAM rules in the Ocelot switches.

Not all actions are demoed, mostly because of difficulty to automate
this from a single board.

For example, policing. We can set up an iperf3 UDP server and client and
measure throughput at destination. But at least with DSA setups, network
namespacing the individual ports is not possible because all switch
ports are handled by the same DSA master. And we cannot assume that the
target platform (an embedded board) has 2 other non-switch generator
ports, we need to work with the generator ports as switch ports (this is
the reason why mausezahn is used, and not IP traffic like ping). When
somebody has an idea how to test policing, that can be added to this
test.

mlnx_qos is a script for configuration of DCB. Despite the name it is not
actually Mellanox-specific in any way. It is currently the only ad-hoc tool
available (in contrast to a daemon that manages an interface on an ongoing
basis). However, it is very verbose and parsing out error messages is not
really possible. Add a wrapper that makes it easier to use the tool.

6e0972e0c5 selftests: forwarding: devlink_lib: Split devlink_..._set() into save & set
Changing pool type from static to dynamic causes reinterpretation of
threshold values. They therefore need to be saved before pool type is
changed, then the pool type can be changed, and then the new values need
to be set up.

For that reason, set cannot subsume save, because it would be saving the
wrong thing, with possibly a nonsensical value, and restore would then fail
to restore the nonsensical value.

Thus extract a _save() from each of the relevant _set()'s. This way it is
possible to save everything up front, then to tweak it, and then restore in
the required order.

cbb58368fb netdevsim: add support for flash_update overwrite mask
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.

bc75c054f0 devlink: convert flash_update to use params structure
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.

ffff9c9cb4 selftests: mlxsw: Reduce runtime of tc-police scale test
Currently, the test takes about 626 seconds to complete because of an
inefficient use of the device's TCAM. Reduce the runtime to 202 seconds
by inserting all the flower filters with the same preference and mask,
but with a different key.

In particular, this reduces the deletion of the qdisc (which triggers
the deletion of all the filters) from 66 seconds to 0.2 seconds. This
prevents various netlink requests from user space applications (e.g.,
systemd-networkd) from timing-out because RTNL is not held for too long
anymore.

4d59e59cf4 selftests: netdevsim: Always initialize 'RET' variable
The variable is used by log_test() to check if the test case completely
successfully or not. In case it is not initialized at the start of a
test case, it is possible for the test case to fail despite not
encountering any errors.

Example:

```
...
TEST: Trap group statistics                                         [ OK ]
TEST: Trap policer                                                  [FAIL]

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.

Fix by adding missing initialization of the variable.
