Create a test that changes a VLAN ID from 200 to 300. We also need to modify the preferences of the filters installed for the other rules so that they are unique, because we now install the "tc-vlan modify" filter in VCAP IS1 only temporarily, and we need to perform the deletion by filter preference number.

2020-10-02selftests: ocelot: add some example VCAP IS1, IS2 and ES0 tc offloadsVladimir Oltean
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. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2020-09-30selftests: mlxsw: qos_lib: Add a wrapper for running mlnx_qosPetr Machata
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.

2020-09-30selftests: forwarding: devlink_lib: Split devlink_..._set() into save & setPetr Machata
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.

2020-09-25netdevsim: add support for flash_update overwrite maskJacob Keller
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.

2020-09-25devlink: convert flash_update to use params structureJacob Keller
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.

2020-08-24selftests: mlxsw: Reduce runtime of tc-police scale testIdo Schimmel
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.
