However, the key length and the number of RETA entries are fixed to 40B and 128 entries respectively. This is done in order to simplify the design, but may be revisited later as the Virtio spec provides this flexibility. Note that only VIRTIO_NET_F_RSS support is implemented, VIRTIO_NET_F_HASH_REPORT, which would enable reporting the packet RSS hash calculated by the device into mbuf.rss, is not yet supported. Regarding the default RSS configuration, it has been chosen to use the default Intel ixgbe key as default key, and default RETA is a simple modulo between the hash and the number of Rx queues.

While the RSS key value is set again after, this is not the case of the key length. It could cause out of bounds access if the key length parsed is smaller than the one read from rte_eth_dev_rss_hash_conf_get(). This patch restores the key length before the rte_eth_dev_rss_hash_update() call to ensure the RSS key value/length pair is consistent.
