ixgbevf: add support for software timestamps
Add a call to skb_tx_timestamp in the ixgbevf_tx_map function. This enables software timestamping for packets sent over this device driver. The call is placed just prior to when we notify hardware of the new packet, in order to software timestamp as close as possible to when the hardware will transmit.
