IPv4 routing test cases with vhost user interface

[Top] Network Topologies: TG-DUT1-TG 2-node circular topology with VM and single links between nodes.
[Enc] Packet Encapsulations: Eth-IPv4 for IPv4 routing on both links.
[Cfg] DUT configuration: DUT1 is configured with IPv4 routing and two static IPv4 /24 route entries. Qemu Guest is connected to VPP via vhost-user interfaces. Guest is running VPP ip4 interconnecting vhost-user interfaces.
[Ver] TG verification: Test IPv4 packet with IP protocol=61 is sent in one direction by TG on links to DUT1; on receive TG verifies packet for correctness and their IPv4 src-addr, dst-addr and MAC addresses.
[Ref] Applicable standard specifications: RFC791, RFC826, RFC792

Test uses two VRFs to route IPv4 traffic through two vhost-user nterfaces. Both interfaces are configured with IP addresses from the same network. The VM is running VPP IPv4 forwarding to pass packet from one vhost-user interface to the other one. Arguments: - frame_size - Framesize in Bytes in integer. Type: integer - phy_cores - Number of physical cores. Type: integer - rxq - Number of RX queues, default value: ${None}. Type: integer
