There is a build error related to the tracing object. As 'rte_eth_tx_queue_count()' is static inline, application needs to be able to access '__rte_eth_trace_tx_queue_count' tracing object, this is problem in shared library build. Needs to update '.../ethdev/version.map' and add '__rte_eth_trace_tx_queue_count'. I am doing the change in next-net and force push. FYI. Since there was no user of the 'rte_eth_tx_queue_count()' API, not able to detect the issue with this patch. But with testpmd support problem became visible.
