Configure RSS hashing to IP/UDP and check for with PMD support
RSS was enabled when rss=yes is set in the configuration or when multiqueue is being used. But when RSS was enabled the types of packets on which RSS hashing was applied might not be supported by the PMD, as almost every PMD supported a different set of packets.
