This patch adds new selftests in the direct packet access suite, to cover the non-linear case. The first six tests cover the behavior of the bounds check with a non-linear skb. The last test adds a call to bpf_skb_pull_data() to be able to access the packet. Note that the size of the linear area includes the L2 header, but for some program types like cgroup_skb, ctx->data points to the L3 header. Therefore, a linear area of 22 bytes will have only 8 bytes accessible to the BPF program (22 - ETH_HLEN). For that reason, the cgroup_skb test cases access the packet at an offset of 8 bytes.
