[dpdk-dev] [PATCH] net/mlx5: fix tunnel offload detection

[Xueming Li]

PMD driver got random tunnel_en value on ConnextX-4LX NIC, depends on
compile optimization level. The variable was not initialized and
detection logic was absent.

Fixes: 578ff15e ("net/mlx5: add hardware checksum offload for tunnel
packets")
