stable_secret - IPv6 address
This IPv6 address will be used as a secret to generate IPv6
addresses for link-local addresses and autoconfigured
ones. All addresses generated after setting this secret will
be stable privacy ones by default. This can be changed via the
addrgenmode ip-link. conf/default/stable_secret is used as the
secret for the namespace, the interface specific ones can
overwrite that. Writes to conf/all/stable_secret are refused.
It is recommended to generate this secret during installation
of a system and keep it stable after that.
By default the stable secret is unset.

ratelimit - INTEGER
Limit the maximal rates for sending ICMPv6 packets.
