[PATCH v2 0/4] Add duplicate_connect option for ctlr connect requests

[James Smart]

This patch adds a duplicate_connect option option to those supported by
fabric connection requests. When set to true (1), duplicate connections
are allowed. When set to false (0), duplicate connections are rejected.

The option is set in the fabrics layer and acted upon by each transport.

This patch set came about as of this prior patch review:
