Add a test that runs traffic across a port throttled with TBF. The test checks that the observed throughput is within +-5% from the installed shaper. To allow checking both the software datapath and the offloaded one, make the test suitable for inclusion from driver-specific wrapper. Introduce such wrappers for mlxsw.

2020-01-25selftests: Move two functions from mlxsw's qos_lib to libPetr Machata1-24/+0
The function humanize() is used for converting value in bits/s to a human-friendly approximate value in Kbps, Mbps or Gbps. There is nothing hardware-specific in that, so move the function to lib.sh. Similarly for the rate() function, which just does a bit of math to calculate a rate, given two counter values and a time interval.

Mausezahn does not recognize "own" as a keyword on source IP address. As a result, the MC stream is not running at all, and therefore no UC degradation can be observed even in principle. Fix the invocation, and tighten the test: due to the minimum shaper configured at the MC TCs, we always expect about 20% degradation. Fail the test if it is lower.

2019-12-18selftests: forwarding: sch_ets: Add test coverage for ETS QdiscPetr Machata2-0/+95
This tests the newly-added ETS Qdisc. It runs two to three streams of traffic, each with a different priority. ETS Qdisc is supposed to allocate bandwidth according to the DRR algorithm and given weights. After running the traffic for a while, counters are compared for each stream to check that the expected ratio is in fact observed. In order for the DRR process to kick in, a traffic bottleneck must exist in the first place. In slow path, such bottleneck can be implemented by wrapping the ETS Qdisc inside a TBF or other shaper. This might however make the configuration unoffloadable. Instead, on HW datapath, the bottleneck would be set up by lowering port speed and configuring shared buffer suitably. Therefore the test is structured as a core component that implements the testing, with two wrapper scripts that implement the details of slow path resp. fast path configuration.

2019-11-15selftests: mlxsw: Adjust test to recent changesIdo Schimmel1-2/+6
mlxsw does not support VXLAN devices with a physical device attached and vetoes such configurations upon enslavement to an offloaded bridge. Commit 0ce1822c2a08 ("vxlan: add adjacent link to limit depth level") changed the VXLAN device to be an upper of the physical device which causes mlxsw to veto the creation of the VXLAN device with "Unknown upper device type". This is OK as this configuration is not supported, but it prevents us from testing bad flows involving the enslavement of VXLAN devices with a physical device to a bridge, regardless if the physical device is an mlxsw netdev or not. Adjust the test to use a dummy device as a physical device instead of a mlxsw netdev.

2019-09-27mlxsw: spectrum: Clear VLAN filters during port initializationIdo Schimmel1-7/+0
When a port is created, its VLAN filters are not cleared by the firmware. This causes tagged packets to be later dropped by the ingress STP filters, which default to DISCARD state. The above did not matter much until commit b5ce611fd96e ("mlxsw: spectrum: Add devlink-trap support") where we exposed the drop reason to users. Without this patch, the drop reason users will see is not consistent. If a port is enslaved to a VLAN-aware bridge and a packet with an invalid VLAN tries to ingress the bridge, it will be dropped due to ingress STP filter. If the VLAN is later enabled and then disabled, the packet will be dropped by the ingress VLAN filter despite the above being a seemingly NOP operation. Fix this by clearing all the VLAN filters during port initialization. Adjust the test accordingly.

2019-03-28selftests: mlxsw: qos_mc_aware: Configure shared buffersPetr Machata1-0/+19
This test runs two streams of traffic from two independent ports to create congestion on one egress port. It is necessary to configure the shared buffer thresholds correctly, to make sure that there is traffic from both streams in the shared buffer. Only then can the test actually test prioritization among these streams. Without this configuration, it is possible, that one of the streams takes all of port-pool quota, and the other stream is not even admitted, thus invalidating the result. On Spectrum-1, this is not a problem, because MC traffic uses a separate pool. But for Spectrum-2, MC and UC share the same pool, and the correct configuration is important.
