Hmm, I *think* this is exactly what I need.
To understand it correctly, I have to set per port group_fwd_mask for both slaves
of the bridge then it will forward anything (except for PAUSE frames)?
Is there a reason why this knob is not documented in Documentation/ABI/testing/sysfs-class-net?
Thanks,
