From 8d80d04a521d4acf949a449403040c38ec648f57 Mon Sep 17 00:00:00 2001 From: Moni Shoua Date: Sun, 6 Dec 2015 18:07:39 +0200 Subject: [PATCH] net/mlx4_core: Use both physical ports to dispatch link state events to VF Under HA mode, the link down event should be sent to VFs only if both ports are down.
