From 5c50f1d18f6bdd8ff8d274479b8bf0d89ab5a47d Mon Sep 17 00:00:00 2001 From: Andrew Boyer Date: Mon, 28 Aug 2017 16:11:59 -0400 Subject: [PATCH] IB/rxe: Handle NETDEV_CHANGE events Without this fix, ports configured on top of ixgbe miss link up notifications. ibv_query_port() will continue to return IBV_PORT_DOWN even though the port is up and working.
