From 03a1dd382c4e2dee654161b656f6ff2528e198aa Mon Sep 17 00:00:00 2001 From: Alaa Hleihel Date: Mon, 1 Jun 2020 15:40:44 -0400 Subject: [PATCH 291/312] [netdrv] net/mlx5e: IPoIB, Enable loopback packets for IPoIB interfaces Message-id: <20200601154102.25980-22-ahleihel@redhat.com> Patchwork-id: 315729 Patchwork-instance: patchwork O-Subject: [RHEL8.3 BZ 1842258 21/39] net/mlx5e: IPoIB, Enable loopback packets for IPoIB interfaces Bugzilla: 1842258 RH-Acked-by: Honggang Li RH-Acked-by: Kamal Heib RH-Acked-by: Marcelo Leitner RH-Acked-by: Jarod Wilson Bugzilla: http://bugzilla.redhat.com/1842258 Upstream: git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next.git , branch: master commit 80639b199c9ca87444da218ba0e7511946452dd4 Author: Erez Shitrit Date: Sun May 3 13:01:37 2020 +0300 net/mlx5e: IPoIB, Enable loopback packets for IPoIB interfaces Enable loopback of unicast and multicast traffic for IPoIB enhanced mode. This will allow interfaces with the same pkey to communicate between them e.g cloned interfaces that located in different namespaces.
