net: dsa: sja1105: Add logic for TX timestamping
On TX, timestamping is performed synchronously from the port_deferred_xmit worker thread. In management routes, the switch is requested to take egress timestamps (again partial), which are reconstructed and appended to a clone of the skb that was just sent. The cloning is done by DSA and we retrieve the pointer from the structure that DSA keeps in skb->cb. Then these clones are enqueued to the socket's error queue for application-level processing.
