How can I spoof my mac address on Bluestacks? My Bluestacks is rooted already with terminal installed. (Busybox 1.21.1)

Thus far, I have tried


Mac Address Ghost - App runs, but simply does spoof MAC
Xprivacy - xposed framework keeps getting seg faults upon installation
# ip link set eth0 xx:xx:xx:xx:xx:xx - Operation not supported on transportation endpoint
# busybox ifconfig eth0 hw ether 00:11:22:33:44:55 - Operation not supported


Has anyone achieved this before or know of a way to change the mac address of Bluestacks?
Unzip initrd.img in c:\programdata\android\ folder (by default). It's a GZIP format.

Next, you should edit initrd file with hex editor.
Find your address,
for example 
02C6400100C6400200C6400362C6400473C6400574

And Replace 02:00:00:64:73:74 bytes with your hex bytes (MAC ADDRESS)

Gzip initrd to initrd.img and replace original file
