This patchset was split from [1] and includes non-functional changes aimed at making it easier to add additional netlink attributes later on. Future extensions are available here [2]. The idea behind these patches is to create an MDB configuration structure into which netlink messages are parsed into. The structure is then passed in the entry creation / deletion call chain instead of passing the netlink attributes themselves. The same pattern is used by other rtnetlink objects such as routes and nexthops. I initially tried to extend the current code, but it proved to be too difficult, which is why I decided to refactor it to the extensible and familiar pattern used by other rtnetlink objects. Tested using existing selftests and using a new selftest that will be submitted together with the planned extensions. v2: * Patch #1: Remove 'skb' argument from br_mdb_config_init(). * Patch #1: Mark 'nlh' argument as 'const'. * Patch #4: Pass 'cfg' as 'const'. * Patch #5: Pass 'cfg' as 'const'. * Patch #9: New patch.
