printing of link speed in proc-info - comparison of rate vs link_speed in testpmd - printing of link speed in testpmd as %u Mbps - division by 1000 in test-pipeline - link speed printing in doc/guides/sample_app_ug/link_status_intr.rst - link speed printing in many-many examples IMHO, it is not nice to print UING32_MAX and let use guess what it means.
