From: Sunil Kumar Kori <sk...@marvell.com>
hdr_lens is used to maintain header lengths after parsing packets.
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.
