From 4e4081673445485aa6bc90383bdb83e7a96cc48a Mon Sep 17 00:00:00 2001 From: Matan Barak Date: Thu, 14 Jan 2016 17:47:02 +0200 Subject: [PATCH] IB/mlx4: Initialize hop_limit when creating address handle Hop limit value wasn't copied from attributes when ah was created. This may influence packets for unconnected services to get dropped in routers when endpoints are not in the same subnet.
