Ido Schimmel 76dd072813 ipv6: Fix crash when IPv6 is administratively disabled ... The global 'raw_v6_hashinfo' variable can be accessed even when IPv6 is administratively disabled via the 'ipv6.disable=1' kernel command line option, leading to a crash [1]. Fix by restoring the original behavior and always initializing the variable, regardless of IPv6 support being administratively disabled or not.
