Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

|
* 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.
