We could specify something like:
The ndo_start_xmit operation for this interface either does not
modify the given skb or modifies it idempotently. A single skb
may be transmitted repeatedly on a single queue of this
interface, but not on multiple queues or on multiple interfaces.
Does that look correct?
Ben.
