Subject: [dpdk-dev] [PATCH 08/17] mlx5: use alternate method to configure promiscuous mode
Date: Mon,  5 Oct 2015 19:54:43 +0200	[thread overview]
Message-ID: <1444067692-29645-9-git-send-email-adrien.mazarguil@6wind.com> (raw)
In-Reply-To: <1444067692-29645-1-git-send-email-adrien.mazarguil@6wind.com>

From: Olga Shern <olgas@mellanox.com>

Promiscuous mode was historically enabled by adding a specific flow with
type IBV_FLOW_ATTR_ALL_DEFAULT to each hash RX queue, but this method is
deprecated. It is now simply enabled by omitting destination MAC addresses
from basic flow specifications.
