Subject: [PATCH v8 0/2] lib: checksum: Fix issues with checksum tests
Date: Wed, 14 Feb 2024 13:41:01 -0800	[thread overview]
Message-ID: <20240214-fix_sparse_errors_checksum_tests-v8-0-36b60e673593@rivosinc.com> (raw)

The ip_fast_csum and csum_ipv6_magic tests did not work on all
architectures due to differences in endianness and misaligned access
support. Fix those issues by changing endianness of data and aligning
the data.

Signed-off-by: Charlie Jenkins <charlie@rivosinc.com>

Changes in v8:
- Change ipv6_magic test case to use memcpy to avoid misalignment
- Add Guenter's tested-by to patch 1 but not patch 2 since the later has
  changed
