What's with Dell and MAC Address Cloning on Broadcom network adapters?

The cable broadband connections and modems from my local cable provider are locked to the MAC Address of the network adapter of the computer connected to it, so whenever another computer needs to connect to the same connection, I clone the MAC Address of the original computer to the new computer.  That way, the connection thinks it's the same computer and it's fast and painless - I wouldn't have to reset the cable connection every single time I change connection from one computer to another.

 

But whenever I need to connect to such a connection (say troubleshooting at a friend's house), I cannot take my Dell notebooks to "show off" without modifications.  Why?  Dell has removed from their Broadcom network adapter drivers the ability to clone MAC Address on every new Dell notebook I come across, and I cannot clone any MAC Address to these notebooks network adapters, and I'm forced to spend time searching for a generic Broadcom driver elsewhere in order to add back the MAC Address function. 

 

I have posted question here in the past on how to clone the MAC Address without this function in the driver but no one seemed to have an answer, so what is Dell's rationale for removing this ability on their own Broadcom network adapter drivers?
