From eab3ca48580c1599da754c621c1a941be27d3e9c Mon Sep 17 00:00:00 2001 From: Gregory Etelson Date: Mon, 16 Nov 2020 16:02:20 +0200 Subject: [PATCH] net/mlx5: fix structure passing method in function call 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.
