bridge: mcast: Allow user space to add (*, G) with a source list and filter mode
Add new netlink attributes to the RTM_NEWMDB request that allow user
space to add (*, G) with a source list and filter mode.
The RTM_NEWMDB message can already dump such entries (created by the
kernel) so there is no need to add dump support. However, the message
contains a different set of attributes depending if it is a request or a
response. The naming and structure of the new attributes try to follow
the existing ones used in the response.
Request:
[ struct nlmsghdr ]
[ struct br_port_msg ]
[ MDBA_SET_ENTRY ]
struct br_mdb_entry
[ MDBA_SET_ENTRY_ATTRS ]
[ MDBE_ATTR_SOURCE ]
struct in_addr / struct in6_addr
[ MDBE_ATTR_SRC_LIST ] // new
[ MDBE_SRC_LIST_ENTRY ]
[ MDBE_SRCATTR_ADDRESS ]
struct in_addr / struct in6_addr
[ ...]
[ MDBE_ATTR_GROUP_MODE ] // new
u8
Response:
[ struct nlmsghdr ]
[ struct br_port_msg ]
[ MDBA_MDB ]
[ MDBA_MDB_ENTRY ]
[ MDBA_MDB_ENTRY_INFO ]
struct br_mdb_entry
[ MDBA_MDB_EATTR_TIMER ]
u32
[ MDBA_MDB_EATTR_SOURCE ]
struct in_addr / struct in6_addr
[ MDBA_MDB_EATTR_RTPROT ]
u8
[ MDBA_MDB_EATTR_SRC_LIST ]
[ MDBA_MDB_SRCLIST_ENTRY ]
[ MDBA_MDB_SRCATTR_ADDRESS ]
struct in_addr / struct in6_addr
[ MDBA_MDB_SRCATTR_TIMER ]
