  59 - Add logic for easier use of the HASH table: First write MAC address to some
  60   register. Then issue a command. CRC is calculated from this MAC and appropriate
  61   bit written to the HASH register.
  62
  63 - In loopback rx_clk is not looped back. Possible CRC error. Consider if usage of
  64   additional logic is necessery (FIFO for looping the data).
  65
  66 - When sending frames bigger than MaxFL, MaxFL is sent, BD marked as finished,
  67   TxB_IRQ interrupt is set and MTxErr is set for a short period. Fix MTxErr or
  68   prevent sending too big frames or set TxE_IRQ instead.
