[dpdk-dev] [PATCH] ethdev: avoid blocking telemetry callback for link status

[Bruce Richardson]

When querying the link status via telemetry interface, we don't want the
client to have to wait for multiple seconds for a reply. Therefore use
"rte_eth_link_get_nowait()" rather than "rte_eth_link_get()" in the
telemetry callback.
