+ * A Link-Level Sockaddr may specify the interface in one of two
+ * ways: either by means of a system-provided index number (computed
+ * anew and possibly differently on every reboot), or by a human-readable
+ * string such as "il0" (for managerial convenience).
+ *
+ * Census taking actions, such as something akin to SIOCGCONF would return
+ * both the index and the human name.
+ *
+ * High volume transactions (such as giving a link-level ``from'' address
+ * in a recvfrom or recvmsg call) may be likely only to provide the indexed
+ * form, (which requires fewer copy operations and less space).
+ *
+ * The form and interpretation  of the link-level address is purely a matter
+ * of convention between the device driver and its consumers; however, it is
+ * expected that all drivers for an interface of a given if_type will agree.
