[dpdk-dev] [PATCH] net/mlx5: optimize tunnel offload index pool

[Suanming Mou]

Currently, when creating the index pool, if the trunk size is not
configured, the index pool default trunk size will be 4096.

The maximum tunnel offload supported now is 256(MLX5_MAX_TUNNELS),
create the index pool with trunk size 4096 wastes the memory.

This commits changes the tunnel offload index pool trunk size to
MLX5_MAX_TUNNELS to save the memory.
