Commit Message

MAC drivers are expected to invoke the transmit time stamping hook in
order to support both software time stamping and PHY time stamping.
This patch adds the missing hook.  In addition, drivers calling
netif_rx() should first check for PHY time stamping by calling
skb_defer_rx_timestamp().
