Subject: [PATCH net-next 0/3] net: bridge: convert multicast to generic rhashtable

Hi,
The current bridge multicast code uses a custom rhashtable
implementation which predates the generic rhashtable API. Patch 01
converts it to use the generic kernel rhashtable which simplifies the
code a lot and removes duplicated functionality. The convert also makes
hash_elasticity obsolete as the generic rhashtable already has such
checks and has a fixed elasticity of RHT_ELASTICITY (16 currently) so we
emit a warning whenever elasticity is set and return RHT_ELASTICITY when
read (patch 02). Since now we have the generic rhashtable which
autoshrinks we can be more liberal with the default hash maximum so patch
03 increases it to 4096 and moves it to a define in br_private.h.

Thanks,
 Nik
