I want to pass through a NIC to my VM for use with promisc mode, so it can do network monitoring. I have another NIC which Unraid is using for normal ops.  I read here https://forums.unraid.net/topic/37959-guide-passing-through-network-controllers-to-unraid-6-virtual-machines/ that all I need to do is add pci-stub.ids=[id] to the startup config but after doing that and rebooting, the NIC is still in use by Unraid and I can't do a port down on it because it's eth0. lspci shows: 08:0
