2019-09-27mlxsw: spectrum: Clear VLAN filters during port initializationIdo Schimmel
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 Machata
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.

2019-02-01selftests: mlxsw: Update ping limitsPetr Machata
The current ping intervals are too short for running mirroring tests in simulator. This leads to ping sending a follow-up ping before the reply arrives, thus sending more than the requested 10 ICMP requests. This traffic is seen at the counters, and causes spurious failures.
