OID_GEN_CO_VENDOR_ID
A 3-byte IEEE-registered vendor code, followed by a single byte that the vendor assigns to identify a particular NIC.
The IEEE code uniquely identifies the vendor and is the same as the three bytes appearing at the beginning of the NIC hardware address.
Vendors without an IEEE-registered code should use the value 0xFFFFFF.
