    nfp: remove false positive offloads in flower vxlan · 0115552e
    John Hurley authored
    Pass information to the match offload on whether or not the repr is the
    ingress or egress dev. Only accept tunnel matches if repr is the egress
    dev.
    
    This means rules such as the following are successfully offloaded:
    tc .. add dev vxlan0 .. enc_dst_port 4789 .. action redirect dev nfp_p0
    
    While rules such as the following are rejected:
    tc .. add dev nfp_p0 .. enc_dst_port 4789 .. action redirect dev vxlan0
    
    Also reject non tunnel flows that are offloaded to an egress dev.
    Non tunnel matches assume that the offload dev is the ingress port and
    offload a match accordingly.
