From 2e8e70d249e8c5c79bf88bbb36bb68154ab15471 Mon Sep 17 00:00:00 2001 From: Or Gerlitz Date: Thu, 19 Jul 2018 16:17:00 +0000 Subject: [PATCH] net/mlx5e: Set port trust mode to PCP as default The hairpin offload code has dependency on the trust mode being PCP. Hence we should set PCP as the default for handling cases where we are disallowed to read the trust mode from the FW, or failed to initialize it.
