From bafff9741704959e99fb65a7327c017251019a19 Mon Sep 17 00:00:00 2001 From: Or Gerlitz Date: Thu, 17 Jan 2008 17:03:45 +0200 Subject: IPoIB: Handle bonding failover race for connected neighbours too Move up the code that checks for a situation where the remote GID stored in the ipoib_neigh is different than the one present in the neighbour (handle gratuitous ARP) or that a bonding fail over has happened but the neighbour still has a pointer to an ipoib_neigh created by a different device than the current slave. This will cause the driver to apply the check also for connected mode neighbours.
