  Ok, so from what I understand to get AP mode fully working, firmware
has to adjust TSF -- this seems to be what TX_CMD_FLG_TSF_MSK does;
everything other should be manageable by software.=20

  Btw, the URL unfortunately doesn't mention anything about multicast
frames;  if there something describing this more in detail?
