[dpdk-dev] [PATCH v2 05/54] kni: check status of getting ethdev info

[Andrew Rybchenko]

From: Ivan Ilchenko <ivan.ilche...@oktetlabs.com>

rte_eth_dev_info_get() return value was changed from void to int,
so this patch modify rte_eth_dev_info_get() usage across
app/test/test_kni.c according to its new return type.
