 * The Original Code is  SNIA HBA API Wrapper Library
 *
 * The Initial Developer of the Original Code is:
 *      Benjamin F. Kuo, Troika Networks, Inc. (benk@troikanetworks.com)
 *
 * Contributor(s):
 *      Tuan Lam, QLogic Corp. (t_lam@qlc.com)

 *
 * ************************************************************************
 *
 * Adding on SM-HBA support
 *
 * The implementation includes Three different categories functions to support
 * both HBAAPI and SM-HBA through the same library.
 *
 * SM-HBA unique interface:
 *      1. CHECKLIBRARYANDVERSION(SMHBA) : match SMHBA VSL
 *         Or checking specifically if version is SMHBA beforehand.
 *      2. resolved to ftable.smhbafunctiontable.{interface}
 * HBAAPIV2 unique functions
 *      1. CHECKLIBRARYANDVERSION(HBAAPIV2) : validate and match HBAAPI V2 VSL.
 *         Or checking specifically if version is HBAAPIV2 beforehand.
 *      2. resolved to ftable.functiontable.{interface}
 * Common interface between SM-HBA and HBAAPIV2.
 *      1. CHECKLIBRARY() : to validate the VSL.
 *      2. FUNCCOMMON macro to map the appropriate entry point table
 *          (union ftable).
 *      3. If the interface is not supported by HBAAPI(Version 1)
 *         the funtiion ptr will be set to NULL.
 * Common interface between HBAAPI and HBAAPIV2.
 *      1. Check if version is not SMHBA).
 *      2. ftable.functiontalbe.(interface)

/*
 * Following the similar logic of HBAAPI addaspterevents_callback.
 *
 * Unlike other events Adapter Add Event is not limited to a specific
 * adapter(i.e. no adapter handle is passed for registration) so
 * the event should be passed to all registrants.  The routine below
 * is passed to the VSLs as a callback and when Adapter Add event is detected
 * by VSL it will call smhba_adapteraddevents_callback() which in turn check
 * if the passed userdata ptr matches with the one stored in the callback list
 * and calls the stored callback.
 *
 * For the situation that multiple clients are registered for Adapter Add event
 * each registration is passed to VSLs so VSL may call
 * smhba_adapteraddevents_callback() multiple times or it may call only once
 * since the callback function is same.  For this implemneation, the userdata
 * is stored in HBA_ALLADAPTERSCALLBACK_ELEM so it is expected that VSL call
 * smhba_adapteraddevents_callback() only once and
 * smhba_adapteraddevents_callback() will call the client callback with proper
 * userdata.
