Subject: [dpdk-dev] [PATCH v2 02/13] net/failsafe: check code of promiscuous mode switch
Date: Mon, 9 Sep 2019 12:58:39 +0100
Message-ID: <1568030331-16526-3-git-send-email-arybchenko@solarflare.com> (raw)
In-Reply-To: <1568030331-16526-1-git-send-email-arybchenko@solarflare.com>

From: Ivan Ilchenko <Ivan.Ilchenko@oktetlabs.ru>

rte_eth_promiscuous_enable()/rte_eth_promiscuous_disable() return
value was changed from void to int, so this patch modify usage
of these functions across net/failsafe according to new return type.

Try to keep promiscuous mode consistent across all active
devices in the case of failure.
