2020-06-08nat: more long read after short write optimizationKlement Sekera1-129/+154
Replace whitespread (mis)use of snat_session_key_t by proper function arguments where applicable and inline functions to calculate hash keys instead of using structs for that. Make all hash tables use same network byte order port so that there is no longer a discrepancy between static mappings using host byte order while in2out/out2in tables using network byte order.
