skb_tx_timestamp9
Driver hook for transmit timestamping
Usage
void skb_tx_timestamp(struct sk_buff * skb);
Arguments
skb
A socket buffer.
Overview
Ethernet MAC Drivers should call this function in their hard_xmit function immediately before giving the sk_buff to the MAC hardware.
Specifically, one should make absolutely sure that this function is called before TX completion of this packet can trigger. Otherwise the packet could potentially already be freed.
