[dpdk-dev] [PATCH] net/mlx5: add Rx checksum offload flag return bad

[Jiawei Zhu <17826875952@163.com>]

From: Jiawei Zhu <zhujiawei12@huawei.com>

When open the rx checksum offload and receive the wrong checksum,
add the ol_flags return bad. And it's not best to use multiplication
and division here.
