Subject: [PATCH net-next v2 0/9] bridge: mcast: Preparations for EVPN extensions

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.
