MAC address vendor code

MAC (Media Access Control) address is a 6 byte HEX code. The first 3 byte is vendor code.  The below list is a list of vendor code.  It is useful for identify the vendor of the NIC connected, in order to guess which host the packet belongs to (e.g. the packet from an iPhone, Broadcom NIC, Realtek NIC, etc).
