New submission from STINNER Victor <vstin...@python.org>:
My FreeBSD VM has a NIC with the IPv6 address fe80::5054:ff:fe9: local-link
IPv6 address. It's used by uuid._netstat_getnode() as a MAC address, but it
seems like this IPv6 address doesn't respect RFC 4122 and so should be skipped.
_find_mac_under_heading() should reject IPv6 address: only use MAC address.
vstinner@freebsd$ uname -a
FreeBSD freebsd 12.1-RELEASE-p2 FreeBSD 12.1-RELEASE-p2 GENERIC amd64

It's using a qemu VM run by virt-manager.
fe805054fffe9 seems to be the MAC address of my vtnet network interface:
