The solution is to save the PTP time before a reset and restore it after the reset is done. The value of the PTP time is saved before a reset and we use the difference from CLOCK_MONOTONIC from reset time to now, to correct what's going to be the new PTP time. This is heavily inspired by commit bf4bf09bdd91 ("i40e: save PTP time before a device reset").

As this behaviour seems contrary to the expectations of the IEEE 802.1Q standard (section 8.6.9, especially 8.6.9.4.5), let's start by rejecting these types of schedules. If this is too limiting, we can for example, setup a timer to configure the BASET registers closer to the start time, only blocking the packets for a "short" while.
