| * 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. |
