There are some CFE variants that start with 'cfe-vd' instead of 'cfe-v', such
as the one used in the Huawei HG556a: "cfe-vd081.5003". In this case, the CFE
version is stored as is (string vs number bytes).
Some newer devices have an additional version number, such as the Comtrend
VR-3032u: "1.0.38-112.118-11".
Finally, print the string as is if the version doesn't start with "cfe-v" or
"cfe-vd", but starts with "cfe-".
