[dpdk-dev] [PATCH v3 3/6] net/mlx5: fix structure passing method in function call

Mon Nov 16 10:13:23 CET 2020
Tunnel offload implementation introduced 64 bit-field flow_grp_info
structure. Since the structure size is 64 bits, the code passed that
type by value in function calls.
The patch changes that structure passing method to reference.
Fixes: 4ec6360de37d ("net/mlx5: implement tunnel offload")
