- Add logic for easier use of the HASH table: First write MAC address to some
54
  register. Then issue a command. CRC is calculated from this MAC and appropriate
55
  bit written to the HASH register.

- When sending frames bigger than MaxFL, MaxFL is sent, BD marked as finished,
61
  TxB_IRQ interrupt is set and MTxErr is set for a short period. Fix MTxErr or
62
  prevent sending too big frames or set TxE_IRQ instead.
