[dpdk-stable] [PATCH v2 60/67] net/mlx5: fix calculation of Tx TSO inline room size

[Yongseok Koh]

[ backported from upstream commit 95d7e115be89f071d672d9cfd5c0eb1b23fce5fc ]

rdma-core doesn't add up max_tso_header size to max_inline_data size. The
library takes bigger value between the two.

Fixes: 43e9d9794cde ("net/mlx5: support upstream rdma-core")
