| help |
| Additional receive skb headroom. Note, that driver |
| will always reserve at least 2 bytes to make IP header |
| aligned, so usually there is no need to add any additional |
| headroom. |
| |
| If unsure, set to 0. |

| Enable this if EMAC attached to a PHY which doesn't generate |
| RX clock if there is no link, if this is the case, you will |
| see "TX disable timeout" or "RX disable timeout" in the system |
| log. |
| |
