trex: Support of SCAPY frame definition
T-Rex implementation in vsperf was improved to support: * SCAPY frame definition, so additional network protocols can be generated by T-Rex and sent towards DUT * VLAN configuration defined by TRAFFIC['vlan'] * enable or disable L2, L3, L4 and VLAN protocols as configured by TRAFFIC dictionary VSPERF documentation was updated with examples of SCAPY frame definition usage.
