commit c13ce47c64ea8f14e77eecb40d1e7c2ac667f898 upstream.
For N2N topology, ELS Passthrough is used to send PLOGI. On failure of ELS pass through PLOGI, driver flipped over to using LLIOCB PLOGI for N2N. This is not consistent. Delete the session to restart the connection where ELS pass through PLOGI would be used consistently.
