Review Comment:
   @daniel-p-carvalho Hi, I've already implemented the SO_TIMESTAMPING + 
MSG_ERRQUEUE TX timestamp delivery and will submitt PRs to NuttX mainline this 
week after resolving the conflict.  The full Linux-style flow is in place: 
sender tags iob->io_conn, driver captures the timestamp and loops the IOB back 
via RX path, userspace retrieves it with recvmsg(MSG_ERRQUEUE) + 
SCM_TIMESTAMPING cmsg.
