[dpdk-dev] [PATCH 12/18] examples/ip_pipeline: check status of getting link info

[Andrew Rybchenko]

From: Igor Romanov <igor.romanov at oktetlabs.ru>

The return value of rte_eth_link_get() and rte_eth_link_get_nowait()
was changed from void to int. Update the usage of the functions
according to the new return type.
