probably I can remove last byte masking as it is already done for the MAC in DB

aligned_last_byte=$(python -c "print format(int(int('$last_byte', 16) & 0b11000000), '02x')") # put mask and take away the 0x prefix
ALIGNED_MAC_ADDRESS=$(python -c "print '$MAC_ADDRESS'[:-2] + '$aligned_last_byte'") # put aligned byte into the end of MAC
