[PATCH 8/8] net: e1000e: Adds hardware supported cross timestamp on e1000e nic

2016-03-02 Thread John Stultz
From: "Christopher S. Hall" Modern Intel systems supports cross timestamping of the network device clock and Always Running Timer (ART) in hardware. This allows the device time and system time to be precisely correlated. The timestamp pair is returned through e1000e_phc_get_syncdevicetime() used
