There are a number of tests that check features of the Linux networking stack. By running them on suitable interfaces, one can exercise the mlxsw offloading code. However none of these tests attempts to push mlxsw to the limits supported by the ASIC.
As an additional wrinkle, the "limits supported by the ASIC" themselves may not be a set of fixed numbers, but rather depend on a profile that determines how the ASIC resources are allocated for different purposes.
This patchset introduces several tests that verify capability of mlxsw to offload amounts of routes, flower rules, and mirroring sessions that match predicted ASIC capacity, at different configuration profiles. Additionally they verify that amounts exceeding the predicted capacity can *not* be offloaded.
