hi,
I have a hard time figuring this out, the kernel says:
...
ix0: <Intel(R) PRO/10GbE PCI-Express Network Driver, Version - 2.5.15> port 
0xecc0-0xecdf mem 0xd9e80000-0xd9efffff,0xd9ff8000-0xd9ffbfff irq 40 at device 
0.0 on pci4
ix0: Using MSIX interrupts with 9 vectors
ix0: Ethernet address: 90:e2:ba:29:c0:54

    vendor     = 'Intel Corporation'
    device     = '82599EB 10-Gigabit SFI/SFP+ Network Connection'
    class      = network
    subclass   = ethernet

but both manuals ixgb and ixgbe mention a different chip, and device
man for ixb says:
...
     ixgb - Intel(R) PRO/10GbE Ethernet driver for the FreeBSD operating sys-
     tem
...
    The ixgb driver provides support for PCI Gigabit Ethernet adapters based
     on the Intel 82597EX Ethernet controller chips.  The driver supports
 
man for ixgbe says:
...
ixgbe - Intel(R) 10Gb Ethernet driver for the FreeBSD operating system
...
    the Intel 82598EB
...

to make things even more confusing, Dell says:
	DELL INTEL X520 DA2 10GBe DP+SERVER ADAPTER PCIE


and finally, there is no man ix

	'will the real ix please stand up?'
