* 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.
