Could you move this description as part of patch 1/3 instead of cover letter? Mostly given this helps understanding the rationale wrt exclusion map which is otherwise lacking from just looking at the patch itself. Assuming you have a bond, how does this look in practice for your mentioned ovs-like data plane in XDP? The map for 'group A' is shared among all XDP progs and the map for 'group B' is managed per prog? The BPF_F_EXCLUDE_INGRESS is clear, but how would this look wrt forwarding from a phys dev /to/ the bond iface w/ XDP? Also, what about tc BPF helper support for the case where not every device might have native XDP (but they could still share the maps)? > To achieve this, I re-implement a new helper bpf_redirect_map_multi() > to accept two maps, the forwarding map and exclude map.
