- * 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.
