Add new bpf_skb_adjust_room() decapsulation flags: - BPF_F_ADJ_ROOM_DECAP_L4_GRE - BPF_F_ADJ_ROOM_DECAP_L4_UDP - BPF_F_ADJ_ROOM_DECAP_IPXIP4 - BPF_F_ADJ_ROOM_DECAP_IPXIP6 These flags let BPF programs describe which tunnel layer is being removed, so later changes can update tunnel-related GSO state accordingly during decapsulation. This patch only introduces the UAPI flag definitions and helper documentation.
