EMAC_STM32F7xx driver supports PTP timestamping for input/output Ethernet frames. Is there a mechanism in Network Middleware drivers to get these timestamps for any TCP/UDP packet received or transmitted?
Yes, PTP protocol is rather complex but it has already been implemented (PTPd) and source code is available. Actually no need to do that again in Middleware layer. The only thing that Middleware should provide for supporting PTP is the ability to have UDP packet timestamp together with received/transmitted packet buffer.
