This is a note to let you know that I have just added a patch titled IB/mlx4: Initialize hop_limit when creating address handle to the linux-3.16.y-queue branch of the 3.16.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.16.y-queue This patch is scheduled to be released in version 3.16.7-ckt24. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.16.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ---8<------------------------------------------------------------ From aac163e2fd03ab89d76828b48f62fbc627954c82 Mon Sep 17 00:00:00 2001 From: Matan Barak <matanb@mellanox.com> Date: Thu, 14 Jan 2016 17:47:02 +0200 Subject: 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.
