Commit
296e07ace0f (flow: Extend struct flow to contain tunnel outer
header.) changed the tunnel ID parameter of flow_extract() from an integer
passed by value to a structure passed by pointer. Before flow_extract()
reads the tunnel ID, it zeros the entire flow parameter. This means that,
if a caller passes the address of the tunnel member of the flow as the
tunnel ID, then flow_extract() zeros the tunnel data before it reads and
copies the tunnel data (that it just zeroed). The result is that the
tunnel data is ignored.
This commit fixes the problem by making the caller that did this use a
separate flow structure instead of trying to be clever.

ovsdb-client: transaction failed (Connection reset by peer)
NOTE: This occurs intermittently depending on how ovsdb-server runs.
Running ovsdb-client on a remote machine increases the possibility.
This is because ovsdb-server closes newly accepted tcp connection.
The following changesets caused it. struct jsonrpc_session::dscp isn't set
based on listening socket's dscp value.
- ovsdb-server creates passive connection and listens on it.
- ovsdb-server accepts connection by ovsdb_jsonrpc_server_run().
The accepted socket inherits from the listening sockets.
ovsdb_jsonrpc_server_run() creates json session, but leaves dscp of
struct jsonrpc_session zero.
- On calling reconfigure_from_db(), it resets dscp value to
all jsonrpc sessions. Eventually jsonrpc_session_set_dscp() is called.
Then jsonrpc_session_force_reconnect() closes the connection.
With this patch,
- struct jsonrpc_session::dscp is correctly set based on
listening sockets dscp value.
- dscp of listening socket is changed dynamically by setsockopt.
This leaves a window where accepted socket may have old dscp.
But it is ignored for now because it would complicates codes
too much.
