The PMD i40e does not support the RSS hash functions ETH_RSS_IPV4 and ETH_RSS_IPV6 (i.e., RSS hash for IPv4 or IPv6 non-fragmented packets). So Gatekeeper cannot work. Nevertheless, i40e has an alternative way to set the needed RSS hash. This patch adds the parameter alternative_rss_hash to struct gatekeeper_if to ask Gatekeeper to try this alternative hash.
