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
