Comment 1 for bug 1848171

After some more investigation I can see that the filters do work with arrays. So, in order to get the filters to work as we want them we would need ideally an array of all interface link speeds e.g. ["1 Gbps", "5 Gbps"], failing that we'd need the interfaces data for each machine in the machines table and we can construct that array by looping through the interfaces (not ideal).
