Enable PTP on ADP3450

[VLabs]

Per this page, the Zyuq7020 GEM provides PTP hardware timestamping:

However, when I enter Linux mode, ethtool reports no hardware timestamping:

root@ADPro:/home/digilent# ethtool -T eth0
Time stamping parameters for eth0:
Capabilities:
	software-transmit     (SOF_TIMESTAMPING_TX_SOFTWARE)
	software-receive      (SOF_TIMESTAMPING_RX_SOFTWARE)
	software-system-clock (SOF_TIMESTAMPING_SOFTWARE)
PTP Hardware Clock: none
Hardware Transmit Timestamp Modes: none
Hardware Receive Filter Modes: none

Is there a way to enable hardware timestamping without re-building the linux image?

Failing that, is there a repository I can use to rebuild the Linux image and still use the Waveforms SDK?

Failing that, could this functionality be enabled by Digilent?
