bridge: export multicast database via netlink
V5: fix two bugs pointed out by Thomas remove seq check for now, mark it as TODO V4: remove some useless #include some coding style fix V3: drop debugging printk's update selinux perm table as well V2: drop patch 1/2, export ifindex directly Redesign netlink attributes Improve netlink seq check Handle IPv6 addr as well This patch exports bridge multicast database via netlink message type RTM_GETMDB. Similar to fdb, but currently bridge-specific. We may need to support modify multicast database too (RTM_{ADD,DEL}MDB). (Thanks to Thomas for patient reviews) Cc: Herbert Xu <herbert@gondor.apana.org.au> Cc: Stephen Hemminger <shemminger@vyatta.com> Cc: "David S.
