wenquan1 95f8c54836 arch/sim: support SO_TIMESTAMPING TX in sim netdriver ... Add TX timestamp loopback support to the simulator network driver. When a packet tagged with io_conn (SO_TIMESTAMPING TX) is sent, the driver clones the packet, generates a software timestamp, and queues it for loopback through the RX path. The protocol layer (UDP/PKT) then delivers the timestamp via MSG_ERRQUEUE. - Add tstampq IOB queue to sim_netdev_s for loopback packets. - In netdriver_send(), clone timestamped packets with realtime clock and notify RX ready. - In netdriver_recv(), return loopback packets before reading from the tap device.
