+/** \defgroup lnet_me Match entries
+ *
+ * A match entry (abbreviated as ME) describes a set of criteria to accept
+ * incoming requests.
+ *
+ * A portal is essentially a match list plus a set of attributes. A match
+ * list is a chain of MEs. Each ME includes a pointer to a memory descriptor
+ * and a set of match criteria. The match criteria can be used to reject
+ * incoming requests based on process ID or the match bits provided in the
+ * request. MEs can be dynamically inserted into a match list by LNetMEAttach(),
+ * and must then be attached to an MD with LNetMDAttach().
