[ovs-dev] [PATCH] python: Fix The SSL connection is not reconnected when the OVSDB Server is restarted

[Guoshuai Li]

When the SSL connection is disconnected by the peer
the client's do_handshake() function throws the exception OpenSSL.SSL.SysCallError
we need to catch the exception and return the exception errno so that the SSL connection can be reconnected.
And the recv() function throws the exception OpenSSL.SSL.ZeroReturnError
This exception refers to TCP connection normal closed, return (0, "")
