You don't need to run windows for that, the nvram (calibration data, 
probably the MAC address and related device specific data) is stored in 
your mainboard's firmware - and exposed to userspace (under linux) via
/sys/firmware/efi/efivars/. You just need to identify the correct file
and copy it to a place where linux expects to find it 
(/lib/firmware/brcm/brcmfmac43340-sdio.txt).
