Take a look at the attached picture.

We always use the "SPF+ shared-NIC (10G)" though in our lab. I don't know that we've ever attempted to get the Intel chip working. There is probably some device tree content, at least, missing for enabling that. --=20 Patrick Williams --X+nYw8KZ/oNxZ8JS Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEBGD9ii4LE9cNbqJBqwNHzC0AwRkFAl9FH10ACgkQqwNHzC0A wRlXCBAAhn0hb8txap8RV4Y0L+qZmEn0K6OzYXzYcRk+r+5f8JblzBEhxuDY+lbf 5ogr+/7EIwVjOznYZE/m6c3KWiyUgP1mRasLwA5rgDsuZ4c9JmIVguWqMJpIPAhC fuxESQLK6X0F3uXZB8VBB+rVn5AkpUM8PktOIuROlVNiVkOWy+WoS7KJPLAC+hSg yX/pfkz5XQBYCsgCa+RL2GB1PHFdH5TJuDkDlKdaWHmvbX86mc00XPrbOuRCXlh/ 4KIVLvicTvoT4Q8gm7Gx/wNvOAyGBNpXd170/Gj0AHA9lQx3HSmbaeraUheepNkO IzwvVjODricUjLFI+gAwQBE4hdQQ7YBa82dQu4CCjUoO9otlfewtHYNnE3GNFLZl EdNAJBFf/fsBsZgC0ql7NwvcCun2robXSDKvscTObxdpEheXBqlFtZJMEfuNapvp DZ7hrz7CcQvypLc+vCuxB1uNN47amQjWsVWj1Ir7/ZATA/1FKhyPrgY4kTPg9KD/ r1EohPsFx5zb6jj8RKFuZOdkx8PJ4ScLznFz3hJGzmNNMilTuHw6LcBu6ZDDqjsz /csh/F+74pwRo4FkIclp25Gy7E/DQi9l5yQh4dkRzukvQ/NAa4E3Jrx4mbgc0EaO BXy7amt5Ga8XdoPcQmi7JvL2FTlLFTYgMlZD0G5dIlqn9Va5/qE= =K4Zp -----END PGP SIGNATURE----- --X+nYw8KZ/oNxZ8JS--
