[dpdk-dev] [PATCH v3 07/13] app/testpmd: check code of promiscuous mode switch

[Andrew Rybchenko]

From: Ivan Ilchenko <Ivan.Ilchenko at 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 app/testpmd
according to new return type.
