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.
