Rather than setting -Bstatic in the linker flags when doing a static link,

When printf()'s stdout is line-buffered for terminal, it is fully
buffered for pipes. So, stdout listener can only get the output
when it is flushed (on program termination, when buffer is filled or

stdout buffer might fill slowly since every stats report could be small.
Also when it is fully filled it might contain a part of the last stats

Most examples have in their makefiles a default RTE_TARGET directory to be

This fixes a potential issue for anyone who continues to build using

explicitly, instead relying on the fact that they were building in a

The iterator RTE_ETH_FOREACH_DEV was introduced in DPDK 17.05.
It uses the function the rte_eth_find_next_owned_by() to get
only ownerless ports. Its API can be considered stable.
So the flag experimental is removed from rte_eth_find_next_owned_by().
The flag experimental is removed from rte_eth_dev_count_avail()
which is the new name of the old function rte_eth_dev_count().
The flag experimental is set to rte_eth_dev_count_total()
