Subject: [PATCH 10/15 net-next,v2] net: flow_offload: add flow_block_cb API
This patch renames:
* struct tcf_block_cb to flow_block_cb.
* struct tc_block_offload to flow_block_offload.
And it exposes the flow_block_cb API through net/flow_offload.h. This
renames the existing codebase to adapt it to this name.
This patch also adds flow_block_cb_splice().
Signed-off-by: Pablo Neira Ayuso <pablo@...filter.org>
