From 3732b9720ffe0fedcadbcb5dc3add1dd0d926bcf Mon Sep 17 00:00:00 2001 From: Aya Levin Date: Fri, 29 Mar 2019 15:38:02 -0700 Subject: [PATCH] net/mlx5: Add rate limit print macros Add rate limited print macros for warning and info level. This protects the system from burst of prints depleting HW resources and spamming dmesg.
