110 * DAT is designed to support multiple DAPL instances simultaneously,
111 * with different dapl libraries originating from different providers.
112 * There is always the possibility of name conflicts, so a dat name
113 * prefix is provided to make a vendor's adapter name unique. This is
114 * especially true of the IBM Access API, which returns adapter
115 * names that are simply ordinal numbers (e.g. 0, 1, 2). If
116 * a vendor doesn't need or want a prefix, it should be left
117 * as a NULL (use "").
118 *
119 * Values that might be used:
120 *  #define VN_PREFIX		"jni"	(JNI: OS Acces API)
121 *  #define VN_PREFIX		"ibm"	(IBM: OS Acces API)
122 *  #define VN_PREFIX		""      (Mellanox: VAPI)
