[dpdk-dev] [PATCH 26/51] examples/l3fwd-power: check status of getting ethdev info

[Andrew Rybchenko]

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

rte_eth_dev_info_get() return value was changed from void to
int, so this patch modify rte_eth_dev_info_get() usage across
examples/l3fwd-power according to its new return type.
