-- . The BG version (g_use_bg=TRUE) functionally works.
-- . The 10G-input version (no BG) needs the DDR3 transpose in fn_beamformer to be in place.
-- . Does the WPFB require SOP/EOP at its inputs? If so, we need to (re)set packet boundaries in the incoming stream of beamlet samples. --FIXME
-- . fn_beamformer now outputs 176/256 beamlets but this might be increased to 192/256 (9.6Gbps) again as its 10G issue is solved.
