+ * A sysctl(3) MIB for generic interface information.  This information
+ * is exported in the net.link.generic branch, which has the following
+ * structure:
+ *
+ * net.link.generic	.system			- system-wide control variables
+ *						  and statistics (node)
+ *			.ifdata.<ifindex>.general
+ *						- what's in `struct ifdata'
+ *						  plus some other info
+ *			.ifdata.<ifindex>.linkspecific
+ *						- a link-type-specific data
+ *						  structure (as might be used
+ *						  by an SNMP agent
+ *
+ * Perhaps someday we will make addresses accessible via this interface
+ * as well (then there will be four such...).  The reason that the
+ * index comes before the last element in the name is because it
+ * seems more orthogonal that way, particularly with the possibility
+ * of other per-interface data living down here as well (e.g., integrated
+ * services stuff).
