From 3fca2ab597d80dbb3052ec691342ca6a8e1e508b Mon Sep 17 00:00:00 2001 From: Gaetan Rivet Date: Fri, 3 Mar 2017 16:39:56 +0100 Subject: [PATCH] net/mlx4: update link status upon probing with LSC If LSC interrupts are enabled, the application expects the link_update ops to be executed by the PMD itself. No link status change event is received upon probing, therefore the link status update must be forced.
