[PATCH 0/3] Add sending TX hardware timestamp for TC ETF Qdisc

4: The socket buffer hardware timestamp is used by the network interface driver to send the actual sending timestamp back to the application. The timestamp is used by the TC ETF before the socket buffer arrives in the network interface driver. Erez Geva (3): Add TX sending

[PATCH 3/3] The TC ETF Qdisc pass the hardware timestamp to the interface driver.
