From: Igor Romanov <igor.romanov at oktetlabs.ru>
User can specify stats period(n). The statistics should be available
to user every n second. But the print_stats() function does not
force stdout to be flushed, so for instance, a user reading testpmd's
stdout through pipe will not be able to read it untill the stdout
buffer is filled.
Fixes: cfea1f3048d1 ("app/testpmd: print statistics periodically")
