modification history
--------------------
01i,09jan12,h_x Move extern "C" after last header file include.
01h,12jul07,kch Re-integrated to support multicast forwarding for IPNET
(WIND00102340).
01g,20may05,kch Redefined cfg_privInitSysctl as function pointer. Moved
ip6MrouteSysctlInit() prototype to sysctlLib.h.
01f,26apr05,kch Allow ip6 mrouter to be scaled out.
01e,19apr05,rp merged from comp_wn_ipv6_mld_interim-dev
01d,28jan05,kc Redefined IF_COPY and IF_ZERO macros.
01c,28dec04,kc Added ipm6_config_params structure. Also added
ip6MrouteSysctlInit() prototype.
01b,23dec04,kc Added pim6_input() and ip6MrouterInstInit() prototypes.
01a,08dec04,kc Integrated Kame changes.
