bpf: Add BPF_F_ADJ_ROOM_DECAP_* flags for tunnel decapsulation
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.
