+ virtual addresses and the size of the mailbox memory in the
+ NetObj.mb_sgl. This structure is used by BECLIB for
+ initial communication with the embedded MCC processor. BECLIB
+ uses the mailbox until MCC rings are created for more efficient
+ communication with the MCC processor.
+
+ If the OSM driver wants to create multiple network interface for more

+ multiple times once for each protection domain. A Maximum of
