From 61db3d7b99a367416e489ccf764cc5f9b00d62a1 Mon Sep 17 00:00:00 2001 From: Moshe Shemesh Date: Thu, 20 Oct 2022 12:25:59 +0300 Subject: [PATCH] net/mlx5: Fix FW tracer timestamp calculation Fix a bug in calculation of FW tracer timestamp. Decreasing one in the calculation should effect only bits 52_7 and not effect bits 6_0 of the timestamp, otherwise bits 6_0 are always set in this calculation.
