Could you please send along the output of lspci -vvv -s 08:00.0 and lspci -vvv -s 08:00.1? The I350 should be supporting SR-IOV and in our lab we have 4 port NICs with the I350 that work fine. Having not seen these daughter cards before I wonder if there is some difference between them. Inspecting the PCIe config might help.
