The six mux blocks muxes one of two frames to the destination port. This is not a simple mux, but it only switches on frame boundaries. This means overlapping frames will not create frame fragments. Frame B is the only one to be forwarded and only after frame A completes. So if the frames overlap, a partial frame may be dropped during the switch. When the output MUX blocks are all bypassing the EE, the EE clock is gated to save power.
