'''
Documentation/networking/ip-sysctl.txt
addr_gen_mode - INTEGER
Defines how link-local and autoconf addresses are generated.
0: generate address based on EUI64 (default)
1: do no generate a link-local address, use EUI64 for addresses generated
from autoconf
2: generate stable privacy addresses, using the secret from
stable_secret (RFC7217)
3: generate stable privacy addresses, using a random secret if unset
