[dpdk-dev] net/mlx5: fix tunnel offload detection
Checks
Commit Message
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")
