When a module or driver is declared, several identification and limit values can be set. These values are stored in the module_info structure.
The module_info structure is intended to be read-only. However, the flow control limits (mi_hiwat and mi_lowat) and the packet size limits (mi_minpsz and mi_maxpsz) are copied to the QUEUE structure, where they can be modified.
ushort_t mi_idnum; /* module ID number */
char *mi_idname; /* module name */
ssize_t mi_minpsz; /* maximum packet size */
size_t mi_hiwat; /* high water mark */
size_t mi_lowat; /* low water mark */
The constant FMNAMESZ, limiting the length of a module's name, is set to eight in this release.
