test_bpf.sh in ubuntu_kernel_selftest/net failed on X-4.4 s390x

[Po-Hsu Lin]

Steps:
  1. Deploy a KVM node with Xenial, install linux-kvm on it.
  2. git clone --depth 1 https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/xenial linux
  3. Run the "net" sub set in the kernel_selftest

Result:
  * test: TPACKET_V1 with PACKET_RX_RING open: No such file or directory
  * test_bpf: [FAIL]
  * selftests: test_bpf.sh [FAIL]

Output:
