Hi Pablo,
do you have any suggestion about this series?
All the following dependency patches is in the nf-next tree now.
netfilter: nf_flow_table_offload: Fix block setup as TC_SETUP_FT cmd
netfilter: nf_flow_table_offload: Fix block_cb tc_setup_type as TC_SETUP_CLSFLOWER
netfilter: nf_flow_table_offload: Don't use offset uninitialized in flow_offload_port_{d,s}nat
netfilter: nf_flow_table_offload: add IPv6 match description
netfilter: nf_flow_table_offload: Correct memcpy size for flow_overload_mangle()
If you feel it's okay, please apply this series. We need the conntrack offload based on tunnel.
And the mlx5e driver patches also depends on this series. I had already test this serires with
mlx5e driver. Thanks!
