Subject: [PATCHv3 net-next 3/3] selftest/ptp: extend test to include ptp_gettimex64any()
Update testptp.c to exercise the new ptp method gettimex64any().
When only -x option is given the PTP_SYS_OFFSET_EXTENDED or
gettimex64() method is exercised while presence of -x with -y
will exercise PTP_SYS_OFFSET_ANY or gettimex64any() method.
-y option is to choose the timebase from available options
of real, mono, or raw.
