Subject: [PATCH net-next 03/12] cls_bpf: remove gen_flags from bpf_offload

cls_bpf now guarantees that only device-bound programs are
allowed with skip_sw.  The drivers no longer pay attention to
flags on filter load, therefore the bpf_offload member can be
removed.  If flags are needed again they should probably be
added to struct tc_cls_common_offload instead.
