- 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.
- If unsure, say N.
