Package macs provides an in-memory mapping of all valid Ethernet MAC address prefixes to their associated organization.
The ValidMACPrefixMap map maps 3-byte prefixes to organization strings. It can be updated using 'go run gen.go' in this directory.
var ValidMACPrefixMap = validMACPrefixMap
ValidMACPrefixMap maps a valid MAC address prefix to the name of the organization that owns the rights to use it. We map it to a hidden variable so it won't show up in godoc, since it's a very large map.
