From 61d3e1d9bc2a1910d773cbf4ed6f587a7a6166b5 Mon Sep 17 00:00:00 2001 From: Nathan Fontenot Date: Mon, 12 Jun 2017 20:47:45 -0400 Subject: [PATCH] ibmvnic: Remove netdev notify for failover resets When handling a driver reset due to a failover of the backing server on the vios, doing the netdev_notify_peers() can cause network traffic to stall or halt. Remove the netdev notify call for failover resets. Signed-off-by: Nathan Fontenot Signed-off-by: David S.
