In connection_or_send_netinfo() we write ``` /* Their address. */ out = cell.payload + 4; len = append_address_to_payload(out, &conn->_base.addr); ``` But the goal here is to say the actual address the conn came from/to, yes? If so, shouldn't it be conn->real_addr? Reported by "troll_un". Targeting this one on 0.2.2 since when we eventually start using the contents of netinfo cells, we'll wish everybody had the fix.
