selftests: net: mscc: ocelot: add test for VLAN modify action

2020-10-11T18:19:04Z

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.

selftests: ocelot: add some example VCAP IS1, IS2 and ES0 tc offloads

2020-10-02T22:40:30Z

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 Signed-off-by: David S. Miller

selftests: mlxsw: Add a PFC test

2020-09-30T21:06:54Z

Add a test for PFC. Runs 10MB of traffic through a bottleneck and checks that none of it gets lost. Signed-off-by: Petr Machata Signed-off-by: David S. Miller

selftests: mlxsw: Add headroom handling test

2020-09-30T21:06:54Z

Add a test for headroom configuration. This covers projection of ETS configuration to ingress, PFC, adjustments for MTU, the qdisc / TC mode and the effect of egress SPAN session on buffer configuration. Signed-off-by: Petr Machata Signed-off-by: David S. Miller

selftests: mlxsw: qos_lib: Add a wrapper for running mlnx_qos

2020-09-30T21:06:54Z

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. Signed-off-by: Petr Machata Signed-off-by: David S. Miller

selftests: forwarding: devlink_lib: Split devlink_..._set() into save & set

2020-09-30T21:06:54Z

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.

selftests: net: add a test for static UDP tunnel ports

2020-09-28T19:50:12Z

Check UDP_TUNNEL_NIC_INFO_STATIC_IANA_VXLAN works as expected. Signed-off-by: Jakub Kicinski Signed-off-by: David S. Miller

selftests: net: add a test for shared UDP tunnel info tables

2020-09-28T19:50:12Z

Add a test run of checks validating the shared UDP tunnel port tables function as we expect. Signed-off-by: Jakub Kicinski Signed-off-by: David S. Miller

netdevsim: fix duplicated debugfs directory

2020-09-26T21:19:08Z

The "ethtool" debugfs directory holds per-netdev knobs, so move it from the device instance directory to the port directory. This fixes the following warning when creating multiple ports: debugfs: Directory 'ethtool' with parent 'netdevsim1' already present!

netdevsim: add support for flash_update overwrite mask

2020-09-26T00:20:57Z

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. Signed-off-by: Jacob Keller Reviewed-by: Jakub Kicinski Signed-off-by: David S. Miller
