 * This file contains OS-Independent support code for Bypass Adapters.  These
 * are adapters which support the capability of operating on a link in an
 * "interposed" manner where two ports are either routed directly two each
 * other (BYPASS) or directed through to the host (NORMAL).  Additionally, in
 * the event the host becomes unresponsive, the adapters support the
 * capability of automatically switching the links to each other (BYPASS) or
 * unconnected (DROP).
