PIM-SM: namespace changes
IPv4:
- make PIM register vifs netns local
- set the netns when a PIM register vif is created
- make PIM available in all network namespaces (if CONFIG_IP_PIMSM_V2)
by adding the protocol handler when multicast routing is initialized
IPv6:
- make PIM register vifs netns local
- make PIM available in all network namespaces (if CONFIG_IPV6_PIMSM_V2)
by adding the protocol handler when multicast routing is initialized
