Possible CRC error. Consider if usage// of additional logic is necessery (FIFO for looping the data).//// Revision 1.1  2002/09/10 10:42:06  mohor// HASH improvement needed.//- Add logic for easier use of the HASH table: First write MAC address to some  register. Then issue a command. CRC is calculated from this MAC and appropriate  bit written to the HASH register.  - In loopback rx_clk is not looped back. Possible CRC error. Consider if usage of  additional logic is necessery (FIFO for looping the data).- When sending frames bigger than MaxFL, MaxFL is sent, BD marked as finished,   TxB_IRQ interrupt is set and MTxErr is set for a short period. Fix MTxErr or   prevent sending too big frames or set TxE_IRQ instead.
