Request to update vmlinux.h (update to at least kernel 6.9)

[Integral-Tech]

• struct bpf_lpm_trie_key has been deprecated since kernel 6.9. It is recommended to use struct bpf_lpm_trie_key_u8 (when the "data" member is needed for byte access) or struct bpf_lpm_trie_key_hdr (when using an alternative type for the trailing flexible array member) instead.
• Since the data member in struct bpf_lpm_trie_key is unused in dae, struct bpf_lpm_trie_key_hdr is obviously a better option. By using the new struct bpf_lpm_trie_key_hdr, the following code in dae should be changed:

你是不是在说这个：daeuniverse/dae#482

没细看你的方案，但是如果是一个在新旧内核都能 CORE 的做法，那非常好！
