netfilter: nf_tables: add flowtable offload control plane
This patch adds the NFTA_FLOWTABLE_FLAGS attribute that allows users to specify the NF_FLOWTABLE_HW_OFFLOAD flag. This patch also adds a new setup interface for the flowtable type to perform the flowtable offload block callback configuration.
