Subject: [PATCH nf,v5 0/4] flow_offload fixes

Hi,

The following patchset contains fixes for the flow_offload infrastructure:

1) Fix possible build breakage before patch 3/4. Both the flow_offload
   infrastructure and OVS define the flow_stats structure. Patch 3/4 in
   this batch indirectly pulls in the flow_stats definition from
   include/net/flow_offload.h into OVS, leading to structure redefinition
   compile-time errors.

2) Remove netns parameter from flow_block_cb_alloc(), this is not
   required as Jiri suggests. The flow_block_cb_is_busy() function uses
   the per-driver block list to check for used blocks which was the
   original intention for this parameter.

3) Rename tc_setup_cb_t to flow_setup_cb_t. This callback is not
   exclusive of tc anymore, this might confuse the reader as Jiri
   suggests, fix this semantic inconsistency.

   Add #include <linux/list.h> to include/net/netfilter/nf_tables_offload.h
   to avoid a compile break with CONFIG_HEADER_TEST=y.

4) Fix block sharing feature: Add flow_block structure and use it,
   update flow_block_cb_lookup() to use this flow_block object.

Please, apply, thank you.
