The following allocations exist so that various 42258141Sgnn * software systems associated with FreeBSD can have unique IDs in the 43258141Sgnn * absence of hardware. The use of OUIs for this purpose is not fully 44258141Sgnn * fleshed out but is now in common use in virtualization technology. 45258141Sgnn * 46258141Sgnn * Allocations from this range are expected to be made using COMMON 47258141Sgnn * SENSE by developers. Do NOT take a large range just because 48258141Sgnn * they're currently wide open. Take the smallest useful range for 49258141Sgnn * your system. We have (2^24 - 2) available addresses (see Reserved 50258141Sgnn * Values below) but that is far from infinite. 51258141Sgnn * 52258141Sgnn * In the event of a conflict arbitration of allocation in this file 53258147Sgnn * is subject to core@ approval. 54258141Sgnn * 55258141Sgnn * Applications are differentiated based on the high order bit(s) of 56258141Sgnn * the remaining three bytes. Our first allocation has all 0s, the 57258141Sgnn * next allocation has the highest bit set. Allocating in this way 58258141Sgnn * gives us 254 allocations of 64K addresses.
