Presumably callers don't need to directly access ts_info, or if they do
we can later provide an accessor function.

[Linuxptp-devel] [PATCH RFC 10/30] interface: Introduce a method to get the time stamping information.

[Richard Cochran]

In order to prevent users from open coding this logic, this patch
provides a method that populates the time stamping information from
the interface label.
