/*
|
|
|
|
|
* OUIs are most often used to uniquely identify network interfaces
|
|
|
|
|
* and occupy the first 3 bytes of both destination and source MAC
|
|
|
|
|
* addresses. The following allocations exist so that various
|
|
|
|
|
* software systems associated with FreeBSD can have unique IDs in the
|
|
|
|
|
* absence of hardware. The use of OUIs for this purpose is not fully
|
|
|
|
|
* fleshed out but is now in common use in virtualization technology.
|
|
|
|
|
*
|
|
|
|
|
* Allocations from this range are expected to be made using COMMON
|
|
|
|
|
* SENSE by developers. Do NOT take a large range just because
|
|
|
|
|
* they're currently wide open. Take the smallest useful range for
|
|
|
|
|
* your system. We have (2^24 - 2) available addresses (see Reserved
|
|
|
|
|
* Values below) but that is far from infinite.
|
|
|
|
|
*
|
|
|
|
|
* In the event of a conflict arbitration of allocation in this file
|
|
|
|
|
* is subject to core@ approval
|
|
|
|
|
*
|
|
|
|
|
* Applications are differentiated based on the high order bit(s) of
|
|
|
|
|
* the remaining three bytes. Our first allocation has all 0s, the
|
|
|
|
|
* next allocation has the highest bit set. Allocating in this way
|
|
|
|
|
* gives us 254 allocations of 64K addresses. Address blocks can be
|
|
|
|
|
* concatenated if necessary.
|
|
|
|
|
*
|
|
|
|
|
* Reserved Values: 0x000000 and 0xffffff are reserved and MUST NOT BE
|
|
|
|
|
* allocated for any reason.
