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. |
