vFW: ARPICMP packets shouldn't be processed by vFW
JIRA: SAMPLEVNF-52 The stats counters are wrong when ARPICMP pkts are received by VFW pipeline in case of HWLB mode as the vFW is trying to process these pkts. The ARPICMP pkts shouldn't be processed by VFW pipeline, as these packets are processed by ARPICMP pipeline in case of HWLB.
