`cur64`, `start64` and `ts_delta` are int64_t. Change format specifiers in fprintf from `"%lu"` to `"%" PRId64` to adapt to 32-bit and 64-bit systems. Signed-off-by: Guo Zhengkui Link: https://lore.kernel.org/r/20220319073730.5235-1-guozhengkui@vivo.com Signed-off-by: Jakub Kicinski

selftests: txtimestamp: fix compilation issue

2021-02-05T04:22:30Z

PACKET_TX_TIMESTAMP is defined in if_packet.h but it is not included in test. Include it instead of otherwise the error of redefinition arrives. Also fix the compiler warning about ambiguous control flow by adding explicit braces.

selftests: txtimestamp: add flag for timestamp validation tolerance.

2020-07-30T23:38:51Z

The txtimestamp selftest sets a fixed 500us tolerance. This value was arrived at experimentally. Some platforms have higher variances. Make this adjustable by adding the following flag: -t N: tolerance (usec) for timestamp validation. Signed-off-by: Jian Yang Acked-by: Willem de Bruijn Signed-off-by: David S. Miller
