| 51 | // In loopback rx_clk is not looped back. Possible CRC error. Consider if usage |
| 52 | // of additional logic is necessery (FIFO for looping the data). |

| 55 | // HASH improvement needed. |

| 58 | |
| 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. |
