The DPE array size is validated\nagainst the total skb length without accounting for ndpoffset, allowing\nout-of-bounds reads when the NDP32 is placed near the end of the NTB.\n\nAdd ndpoffset to the nframes bounds check and use struct_size_t() to\nexpress the NDP-plus-DPE-array size more clearly.\n\nCompile-tested only.",
