Converts an IPv6 link-local address to a MAC address
#!/usr/bin/env python3
'''
thanks https://ben.akrin.com/?p=1347
To convert from an IPv6 link-local address to a MAC address:
- the 1st 64 bits go away (the fe80:: part)
- bit 71 gets flipped (after fe80:: is gone this would be the 7th bit)
- bits 89 through 112 go away (the ff:fe)
