In this implementation we add a new helper to accept two maps: forward map and exclude map. We will redirect the packet to all the interfaces in *forward map*, but exclude the interfaces that in *exclude map*. To achive this I add a new ex_map for struct bpf_redirect_info. in the helper I set tgt_value to NULL to make a difference with bpf_xdp_redirect_map() We also add a flag *BPF_F_EXCLUDE_INGRESS* incase you don't want to create a exclude map for each interface and just want to exclude the ingress interface. The general data path is kept in net/core/filter.c. The native data path is in kernel/bpf/devmap.c so we can use direct calls to get better performace. v3: Based on Toke's suggestion, do the following update a) Update bpf_redirect_map_multi() description in bpf.h. b) Fix exclude_ifindex checking order in dev_in_exclude_map(). c) Fix one more xdpf clone in dev_map_enqueue_multi(). d) Go find next one in dev_map_enqueue_multi() if the interface is not able to forward instead of abort the whole loop. e) Remove READ_ONCE/WRITE_ONCE for ex_map. v2: Add new syscall bpf_xdp_redirect_map_multi() which could accept include/exclude maps directly.
