Are you certain that your Finisar transceivers are 10GbE transceivers
and not Fibre Channel transceivers?  What does dmesg say about NIC
initialization - you might dmesg | grep <driver> and dmesg | grep
<interface> and see what they say.

You might also hunt around to see if there is an Intel NIC support
email address.
