* selftests: mlxsw: Add Bloom delta testNir Dotan2018-12-161-1/+36
| | | | | | | | | | | | | | | | The eRP table is active when there is more than a single rule pattern. It may be that the patterns are close enough and use delta mechanism. Bloom filter index computation is based on the values of {rule & mask, mask ID, region ID} where the rule delta bits must be cleared. Add a test that exercises Bloom filter with delta mechanism. Configure rules within delta range and pass a packet which is supposed to hit the correct rule.

| | | | | | | | | | | | | | | | | When a VXLAN device is attached to an offloaded bridge, or when a front-panel port is attached to a bridge that already has a VXLAN device, mlxsw should offload the existing offloadable FDB entries. Similarly when VXLAN device is downed, the FDB entries are unoffloaded, and the marks thus need to be cleared. Similarly when a front-panel port device is attached to a bridge with a VXLAN device, or when VLAN flags are tweaked on a VXLAN port attached to a VLAN-aware bridge.

| | | | | | | | | | | | | | | | | A so-called "MC-aware" mode has recently been enabled in mlxsw. In MC-aware mode, BUM traffic is handled in a special way so that when a switch is flooded with BUM, UC performance isn't unduly impacted. Without enablement of this mode, a stream of BUM traffic can cause sustained UC throughput drop in excess of 99 %. Add a test for this behavior. Compare how much UC throughput degrades as a stream of broadcast frames floods the switch. A minimal degradation is tolerated to cover for glitches in traffic injection performance.
