This patch series is missing a few things:
1. Taking into the consideration the number of Rx queues requested by a
user in the rte_eth_dev_configure().
2. dev->dev_ops->reta_query used by a rte_eth_dev_rss_reta_query() is
still not initialized for a VF. Thus there is no way to query the
RSS table contents.
3. rte_eth_dev_info_get() returns reta_size == 0 when called for a VF
function.
