From: Sriharsha Basavapatna <sriharsha.basavapa...@broadcom.com> The driver currently uses src port field (along with other fields) in the decap tunnel key, while looking up and adding tunnel nodes. This leads to redundant cfa_decap_filter_alloc() requests to the FW and flow-miss in the flow engine. Fix this by ignoring the src port field in decap tunnel nodes.
