ERROR: Can't change MAC: interface up or not permission: Invalid argument

ERROR: Can't change MAC: interface up or not permission: Invalid argument

So, I was messing around with aircrack & macchanger and following some
tutorials. I typed the following command into the terminal
macchanger --mac 00:11:22:33:44:55 wlan0
and I got the following error
ERROR: Can't change MAC: interface up or not permission: Invalid argument
I have no clue what this means, so i done some digging through google and
come across one article here and if you go the the third comment from the
bottom, someone else has run into the same problem, and there was a reply
in the second comment from the bottom that simply stated.
As you have guessed, this means that the Linux driver for your device
doesn't allow changing the MAC address (whereas the Windows one does).
Unfortunately, there's not much you can do about it, other than patching
the driver yourself or bugging Realtek about it.
Ok, well why is that so? that's pretty stupid, is there any way to get
around this, or what drivers am I supposed to be looking at replacing?
How do we go about "patching the driver"?
