As discussed in mailing list discussion at https://mailarchive.ietf.org/arch/msg/bpf/5LnnKm093cGpOmDI9TnLQLBXyys/ this patch updates the "Legacy BPF Packet access instructions" section to clarify which instructions are deprecated (vs which were never defined and so are not deprecated).

However, these instructions are +carried over from classic BPF. These instructions used an instruction +class of BPF_LD, a size modifier of BPF_W, BPF_H, or BPF_B, and a +mode modifier of BPF_ABS or BPF_IND. However, these instructions are deprecated and should no longer be used. All legacy packet access instructions belong to the "legacy" conformance group instead of the "basic" conformance group. -- 2.40.1
