| 33 | Additional receive skb headroom. Note, that driver |
| 34 | will always reserve at least 2 bytes to make IP header |
| 35 | aligned, so usually there is no need to add any additional |
| 36 | headroom. |

| 44 | Enable this if EMAC attached to a PHY which doesn't generate |
| 45 | RX clock if there is no link, if this is the case, you will |
