If the driver is not in ROS, your only option it to contact support and try to persuade them enough so it’s added… good luck with that.
There is also small possibility beta version of ROS 7 may have the driver, you can try installing it to USB key (so you don’t mess up your existing SSD) and test it. It’s still in beta, but if it works, it will be better than nothing…
Well, his SSD isn’t working for him as it is, so he might just as well try 7.0 beta on that… If that doesn’t work either, he could try CHR under a hypervisor that does know how to talk to those interfaces, assuming that box has enough RAM for it.
I am using a linux/KVM based system with vt-d/IOMMU to pass through the hardware NICs to a Router-VM, running CHR
This is a system, that works already for years an a self-build system with I3-8100 and i310AT Quad-NIC.
Now I purchased a mini PC with i5-6200U and 6x i211AT NICs…and no joy.
However,.using pfsense/opnsense works fine in the VM with NICs in passthrough (as underlying FreeeBSD is using the same driver for both models of these intel based chipsets).
I will try v7beta…otherwie opensense it is.
Edit: yes, ROS image for CHR based on v7beta does have the drivers.
i got one like that…managed to install x86 but no ethernet detected at all…so i gave up
use CHR with virtio-net (kvm) or vmxnet (vmware) driver so you wont get high cpu load or low throughput
