[Linuxptp-devel] timestamp types

[Anil kumar]

Hi,

Cany any one please let me know the difference between timestamp_types
TS_HARDWARE and TS_LEGACY_HW. In the code, SOF_TIMESTAMPING_RAW_HARDWARE
flag is used for TS_HARDWARE type and SOF_TIMESTAMPING_SYS_HARDWARE flag
is used for TS_LEGACY_HW type.

Where are these timestamp values are filled when the two types are used ?
Can we use these flags together ?

Thanks,
Anil

LEGACY is no longer supported by any Linux driver (and it will never
appear again as long as I am maintainer).

So just ignore it, and don't worry about it.
