Subject: net/bonding: check status of getting ethdev info
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=fab234519984b14c394b4948e292f5ecb298a7da;p=dpdk.git

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.
