[dpdk-dev] [PATCH v3 03/13] net/bonding: check code of promiscuous mode switch

[Andrew Rybchenko <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/bonding according to new return type.
