Mac forwarding in the sense of linux bridge mac forwarding mechanism which
requires set_rx_mode ndo to be implemented.

Linux-bridge --> mlx5-uplink-rep --> set_rx_mode --> set up mac in HW.  

And the actual forwarding happens in SW bridge? This is just to
configure the Rx filter not to discard on Rx?  

Yes Forwarding happens on the SW bridge, just to register the mac so it
won't get dropped.

Ah! Please respin with a better explanation and calling that out? 
I think it's fair for the reader to assume offload when reading
about representors.
