I’ve not used lwIP before I’m struggling to find a way to
pass this timestamp to the SNTP routine and keep it
reference to the SNTP packet. I have considered storing
this in the pbuf but I’m not keen on modifying the pbuf
without a better understanding the implications of this. I
have also looked at adding this time to the end of the Rx
buffer, then storing this in the pbuf but as this is passed
through the ip_input routine the additional data is stripped
from the buffer as its not part of the original packet.
anyone have any experience of implementing anything similar,
or any ideas or tips of achieving this.
