Move and adjust the base of RSS configuration from util-dpdk-i40e.c to a new file that can be later utilized by other cards. RSS configuration can be configured via rte_flow rules. This is useful for possible future features such as specific header offload (vxlan, nvgre) also implemented via rte_flow rules, as rte_flow rules can be chained via groups and priorities. Ticket: 7337
ixgbe driver requires different configuration of rss rte_flow rule than i40e, with just one generic rule matching all traffic. Ticket: 7337
ice driver has similar approach to setting rte_flow rss rule as i40e, only without explicitly setting queues. Ticket: 7337
mlx5 driver uses only one generic rte_flow rss rule to match all traffic Ticket: 7337
