From fab234519984b14c394b4948e292f5ecb298a7da Mon Sep 17 00:00:00 2001 From: Ivan Ilchenko Date: Thu, 12 Sep 2019 17:42:24 +0100 Subject: [PATCH] net/bonding: check status of getting ethdev info rte_eth_dev_info_get() return value was changed from void to int, so this patch modify rte_eth_dev_info_get() usage across net/bonding according to its new return type.
