- * 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.
