CSIT-661: re-add vring256 tuned CFS for vpp workers and guest-testpmd

1. add vhost tests (L2XBD, L2XC and IP4BASE) with vring set to 256 and tuned CFS setting 2. add vhost tests (L2XBD, L2XC and IP4BASE) with vring set to 256 and default CFS setting Change-Id: I25aae6839d3e621316d35f5c9525389a6faabd56 Signed-off-by: Jan Gelety <jgelety@cisco.com>

+| ... | *[Enc] Packet Encapsulations:* Eth-IPv4 for L2 switching of IPv4. 802.1q
+| ... | tagging is applied on link between DUT1 and DUT2.
+| ... | *[Cfg] DUT configuration:* DUT1 and DUT2 are configured with L2 bridge-
+| ... | domain and MAC learning enabled. Qemu Guest is connected to VPP via
+| ... | vhost-user interfaces. Guest is running DPDK testpmd interconnecting
+| ... | vhost-user interfaces using 5 cores pinned to cpus 5-9 and 2048M
+| ... | memory. Testpmd is using socket-mem=1024M (512x2M hugepages), 5 cores
+| ... | (1 main core and 4 cores dedicated for io), forwarding mode is set to
+| ... | io, rxd/txd=256, burst=64. DUT1, DUT2 are tested with 2p10GE NIC X520
+| ... | Niantic by Intel.
+| ... | *[Ver] TG verification:* TG finds and reports throughput NDR (Non Drop
+| ... | Rate) with zero packet loss tolerance or throughput PDR (Partial Drop
+| ... | Rate) with non-zero packet loss tolerance (LT) expressed in percentage
+| ... | of packets transmitted. NDR and PDR are discovered for different
+| ... | Ethernet L2 frame sizes using either binary search or linear search
+| ... | algorithms with configured starting rate and final step that determines
+| ... | throughput measurement resolution. Test packets are generated by TG on
+| ... | links to DUTs. TG traffic profile contains two L3 flow-groups
+| ... | (flow-group per direction, 253 flows per flow-group) with all packets
+| ... | containing Ethernet header, IPv4 header with IP protocol=61 and static
+| ... | payload. MAC addresses are matching MAC addresses of the TG node
+| ... | interfaces.
+| ... | *[Ref] Applicable standard specifications:* RFC2544.

+| ... | *[Enc] Packet Encapsulations:* Eth-IPv4 for IPv4 routing.
+| ... | *[Cfg] DUT configuration:* DUT1 and DUT2 are configured with IPv4
+| ... | routing and two static IPv4 /24 route entries. Qemu Guest is connected
+| ... | to VPP via vhost-user interfaces. Guest is running DPDK testpmd
+| ... | interconnecting vhost-user interfaces using 5 cores pinned to cpus 5-9
+| ... | and 2048M memory. Testpmd is using socket-mem=1024M (512x2M hugepages),
+| ... | 5 cores (1 main core and 4 cores dedicated for io), forwarding mode is
+| ... | set to mac, rxd/txd=256, burst=64. Scheduler policy is set to SCHED_RR
+| ... | with priority 1 for all Qemu CPUs. DUT1, DUT2 are tested with 2p10GE
+| ... | NIC X520 Niantic by Intel.
+| ... | *[Ver] TG verification:* TG finds and reports throughput NDR (Non Drop
+| ... | Rate) with zero packet loss tolerance or throughput PDR (Partial Drop
+| ... | Rate) with non-zero packet loss tolerance (LT) expressed in percentage
+| ... | of packets transmitted. NDR and PDR are discovered for different
+| ... | Ethernet L2 frame sizes using either binary search or linear search
+| ... | algorithms with configured starting rate and final step that determines
+| ... | throughput measurement resolution. Test packets are generated by TG on
+| ... | links to DUTs. TG traffic profile contains two L3 flow-groups
+| ... | (flow-group per direction, 253 flows per flow-group) with all packets
+| ... | containing Ethernet header, IPv4 header with IP protocol=61 and static
+| ... | payload. MAC addresses are matching MAC addresses of the TG node
+| ... | interfaces.

+| ... | routing and two static IPv4 /24 route entries. Qemu Guest is connected
+| ... | to VPP via vhost-user interfaces. Guest is running DPDK testpmd
+| ... | interconnecting vhost-user interfaces using 5 cores pinned to cpus 5-9
+| ... | and 2048M memory. Testpmd is using socket-mem=1024M (512x2M hugepages),

+| ... | *[Ver] TG verification:* TG finds and reports throughput NDR (Non Drop
+| ... | Rate) with zero packet loss tolerance or throughput PDR (Partial Drop
+| ... | Rate) with non-zero packet loss tolerance (LT) expressed in percentage
+| ... | of packets transmitted. NDR and PDR are discovered for different
+| ... | Ethernet L2 frame sizes using either binary search or linear search
+| ... | algorithms with configured starting rate and final step that determines
+| ... | throughput measurement resolution. Test packets are generated by TG on
+| ... | links to DUTs. TG traffic profile contains two L3 flow-groups
+| ... | (flow-group per direction, 253 flows per flow-group) with all packets
+| ... | containing Ethernet header, IPv4 header with IP protocol=61 and static
+| ... | payload. MAC addresses are matching MAC addresses of the TG node
+| ... | interfaces.
