I've only just plugged this card back in, though I am now on a different computer. My setup is displaying peculiar behaviour as follows:
Onboard NIC Eth0: Cable plugged in - ping works
Dual Port NIC Eth1: Cable plugged in - ping works
Dual Port NIC Eth2: Cable unplugged - ping works
If I swap the port the cable is in:
Onboard NIC Eth0: Cable Plugged in - ping works
Dual Port NIC Eth1: Cable unplugged in - no rely from ping
Dual Port NIC Eth2: Cable plugged in - no reply from ping
Anyone have any bright ideas why an unplugged port responds to a ping? I don't think this is a hardware issue - seems more like a driver issue?
I assume having the onboard ethernet mixed in this IOMMU Group would only matter if I wanted to pass it through to something, that this wouldn't be causing the interface to go up and down as it has been.

Many thanks for any advice.
