In some of the SoC's, the DTE's NCO is synced in hardware with the Ethernet's
1588 Shim NCO (used for time-stamping the packets). We are working on getting
all the future SoC's synced this way (for Ethernet).
In other scenarios, we use an user-space app to perform the sync based on
time-stamps from external hardware sources like the Wi-Fi.
