[CRIU] [PATCH CRIU 06/14] net/ipv6: add devconfs6 array to store config option's names

[Pavel Tikhomirov]

* do not c/r mc_forwarding option it depends on multicast
managment socket existence and is readonly.
* stable_secret can not be handled these way as it is of type string

In addrconf_sysctl_disable->addrconf_disable_ipv6->dev_disable_change:
On addrconf_notify + NETDEV_UP if idev->cnf.mtu6 differs from dev->mtu,
sysctl mtu6 is overwritten.

So changing disable_ipv6 sysctl for some device may change mtu sysctl
for it and we need to restore disable_ipv6 first and only then mtu.
