Hi Elias, This is correct. The patch you mentioned did improve logging: previously those error messages were silently discarded. Here is what happened: support for multiple mac filtering per interface was added a few weeks back. To support that, when you add a bond with lacp, it is now trying to register the lacp multicast ethernet mac so that the underlying interfaces will receive lacp frames. This is not supported in the rdma driver for now, which fallback to always accepting all broadcast/multicast ethernet frames. Patches are welcome 😊 - however the only downsides are that you'll receive all broadcast/multicast ethernet frames regardless of what you're interested in and those error messages.
