From b121fad282f2ff012eca31efe4446dc9c170206a 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 commit 4e4081673445485aa6bc90383bdb83e7a96cc48a upstream. 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.
