[ Upstream commit 4236f114a3ffbbfd217436c08852e94cae372f57 ]
During the xdp_adjust_tail test, probabilistic failure occurs and SKB package
is discarded by the kernel. After checking the issues by tracking SKB package,
it is identified that they were caused by checksum errors. Refer to checksum
of the arch/arm64/include/asm/checksum.h for fixing.
v2: Based on Alexei Starovoitov's suggestions, it is necessary to keep the code
implementation consistent.
Fixes: c6ffd1ff7856 (bpf: add bpf_xdp_adjust_tail sample prog)
