SKB_TX_TIMESTAMP(9)                      Linux Networking                     SKB_TX_TIMESTAMP(9)



NAME
       skb_tx_timestamp - Driver hook for transmit timestamping

SYNOPSIS
       void skb_tx_timestamp(struct sk_buff * skb);

ARGUMENTS
       skb
           A socket buffer.

DESCRIPTION
       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.
