net: bridge: mark hash_elasticity as obsolete
Now that the bridge multicast uses the generic rhashtable interface we can drop the hash_elasticity option as that is already done for us and it's hardcoded to a maximum of RHT_ELASTICITY (16 currently). Add a warning about the obsolete option when the hash_elasticity is set. Signed-off-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
