ptp: add the pin GET/SETFUNC ioctls to the testptp program.
This patch adds a option to the test program that lists the programmable pins on a PTP Hardware Clock device, assuming there are any such pins. A second option lets the user reprogram the auxiliary function of a single pin. Signed-off-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
