 -- Remarks:
 -- . 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.
 -- . URGENT:
---   . We need 9b filter coefficients before we can synthesize! --FIXME
+--   . We need 9b filter coefficients before we can synthesize including the mesh terminals! --FIXME
 --     . Note: the 18b coeffieciens *do* fit and meet timing with only BG (without 10G RX stage).

 --   . Synthesis incl. mesh terminals went OK but used 96% of the logic resources.
