I'm not sure that I like this change. I understand that the "speed" may be the
same but generally FDR10 was supposed to be "better". For all the other speed
checks the string is "Could be" and I know I have used that to grep for any
links which are not at "maximum" (Or "best supported") speed.
For this reason, I don't think it is going to generally be good for customers.
Was there a particular reason you needed to change this?
