Subject: [dpdk-dev] [PATCH v2 22/23] mlx4: disable multicast echo when device is not VF
Date: Tue, 30 Jun 2015 11:28:08 +0200 [thread overview]
Message-ID: <1435656489-27986-23-git-send-email-adrien.mazarguil@6wind.com> (raw)
In-Reply-To: <1435656489-27986-1-git-send-email-adrien.mazarguil@6wind.com>
From: Olga Shern <olgas@mellanox.com>
Multicast loopback must be disabled on PF devices to prevent the adapter
from sending frames back. Required with MOFED 3.0.
