<h2>Changes to existing API:</h2>

-<li>SocketAddressTag was a long-standing API glitch. It was used to replicate
- the RecvFrom effect (i.e., to know the source address of packet) without
- calling RecvFrom.
- This option is more harmful than useful, because in case of tunnels the
- new tag needs to replace the old one. Moreover, there is no real need
- to create a new API when there is a perfectly working one (i.e., RecvFrom).

+ socket recvfrom behavior (i.e., to know the source address of a packet)

+ replace the old one). Moreover, there is no real need

As a consequence, SocketAddressTag has been completely removed from ns-3.
Users can use RecvFrom (for UDP), GetPeerName (for TCP), or similar.
