by iterating over the relevant parts and trying to parse out the
'ResourceSubType'. The content of that is not standardized, but I only
ever found examples that are compatible with vmware, meaning it's
either 'e1000', 'e1000e' or 'vmxnet3' (in various capitalizations; thus
the `lc()`)
As a fallback i used e1000, since that is our default too, and should
work for most guest operating systems.
