struct __rte_aligned | ( | 2 | ) |
Ethernet address: A universally administered address is uniquely assigned to a device by its manufacturer. The first three octets (in transmission order) contain the Organizationally Unique Identifier (OUI). The following three (MAC-48 and EUI-48) octets are assigned by that organization with the only constraint of uniqueness. A locally administered address is assigned to a device by a network administrator and does not contain OUIs. See http://standards.ieee.org/regauth/groupmac/tutorial.html
