Commit Message

Gregory Etelson Nov. 16, 2020, 2:02 p.m. UTC 
  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")
