Clarify availability of PTP(IEEE 1588) on Orin NX

Does the ethernet interface of the Orin NX support hardware PTP(IEEE 1588)?

According to this forum post and the Jetson Orin documentation it should be the same as with the AGX Orin.

Though when testing the hardware I don’t see any /dev/ptp0 on the Orin NX.
It also loads a different network driver (nvethernet for the AGX Orin and r8168 for the Orin NX).

Could you please clarify? This is quite crucial for our product.

PTP is supported on AGX Orin series. Not supported on Orin NX and Orin Nano series.
