net: flow_offload: add flow_block_cb_{priv, incref, decref}()
This patch completes the flow block API to introduce: * flow_block_cb_priv() to access callback private data. * flow_block_cb_incref() to bump reference counter on this flow block. * flow_block_cb_decref() to decrement the reference counter. These functions are taken from the existing tcf_block_cb_priv(), tcf_block_cb_incref() and tcf_block_cb_decref(). Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>
