[PATCH net-next 06/12] mlxsw: spectrum_acl: Set A-TCAM rules in Bloom filter

[Ido Schimmel]

From: Nir Dotan <n...@mellanox.com>

Add calls to eRP module for updating Bloom filter when a rule is
added or removed from the A-TCAM. eRP module will update the Bloom
filter only for cases in which the region has an active eRP table.
