The dpdk nic bind script seems to see them correctly but when running
testpmd with those ports, they always come with link status down.

>From the dpdk_nic_bind script (snip):

Network devices using DPDK-compatible driver
============================================
0000:03:00.0 'Ethernet Connection X552/X557-AT 10GBASE-T' drv=igb_uio unused=
0000:03:00.1 'Ethernet Connection X552/X557-AT 10GBASE-T' drv=igb_uio unused=

After I load the igb_uio module and do the bind, I notice this in dmesg:

[82021.124497] igb_uio: Use MSIX interrupt by default
[82024.368227] ACPI Warning: \_SB_.PCI0.BR2C._PRT: Return Package has
no elements (empty) (20150410/nsprepkg-126)
[82024.378940] igb_uio 0000:03:00.0: uio device registered with irq 36
[82024.384316] ACPI Warning: \_SB_.PCI0.BR2C._PRT: Return Package has
no elements (empty) (20150410/nsprepkg-126)

I am starting testpmd with this command line:

./testpmd -c 0x7  -n 4 -- -i

I have enabled all the ixgbe debugging messages and I have noticed
this messages when testpmd starts:

PMD: ixgbe_device_supports_autoneg_fc(): Device 15ad does not support
flow control autoneg
