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. Signed-off-by: Or Gerlitz <ogerlitz@voltaire.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
