samples: Add generic L3 forwarder tests
A generic throughput test case that can be used as a stub code for a Linux-based VNF configured as an L3 forwarder. Supported context: * Standalone OVSDPDK and SRIOV * Baremetal Code changes: * Allow pmd-cpu-mask and lcore mask for OVS DPDK * router_vnf.py - configures interface IP addresses and static arp entries using ip command * NFVi KPIs * Allow cputune tag for standalone context to be able to PIN on NUMA 1 cpus SRIOV Test cases: * RFC2544 Ethernet framesizes, 128K Flows * 2,4 and 6 ports * 2 and 3 vcpus per port * OVSDPDK Test cases: * RFC2544 Ethernet framesizes, 128K Flows * 2 and 4 ports * 2 vcpus per port * 2 PMD threads per port TODO: * Documentation * Add 6 ports tests References: * router_vnf.py is based on sample_vnf.py * tc_*.yaml files are based on acl/vfw test case files Added unitests Added get_stats to parse ip -s link Change-Id: Id1b969d5420dfcab7c1e695acbd2cd1655747efe Signed-off-by: Dino Simeon Madarang <dinox.madarang@intel.com> Signed-off-by: Kavindya Deegala <kavindya.s.deegala@intel.com> Reviewed-by: Alain Jebara <alain.jebara@intel.com> Reviewed-by: Deepak S <deepak.s@linux.intel.com> Reviewed-by: Emma Foley <emma.l.foley@intel.com> Reviewed-by: Rodolfo Alonso Hernandez <rodolfo.alonso.hernandez@intel.com> Reviewed-by: Ross Brattain <ross.b.brattain@intel.com> Reviewed-by: Edward MacGillivray <edward.s.macgillivray@intel.com> Signed-off-by: Dhaval Patel <dhaval.r.patel@intel.com> Signed-off-by: Ross Brattain <ross.b.brattain@intel.com>
