When port receives different type of packets (say first is VXLAN packet and second is GRE packet). For first packet, L2/L3/L4 lengths are set for inner and outer header alongwith tunnel_len. Now for second packet, tunnel_len is added more than its size it contains stale value which further leads to wrong header pointers. Hence clearing stale information before processing each packet.
