2020-06-08nat: more long read after short write optimizationKlement Sekera15-1060/+1051
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.

2020-05-27nat: fix regarding vm arg for vlib_time_now callElias Rudberg1-1/+2
Change in snat_ipfix_header_create() to use thread-specific vlib_main_t *vm pointer to avoid problems with different threads accessing the same vlib_main_t data structure. This avoids assertion failure when vlib_time_now() is called with a vm corresponding to a different thread.

2020-05-14nat: ED: store both thread&session idx in hashKlement Sekera9-197/+315
By storing thread and session index in hash table we are able to skip multiple hash lookups in multi-worker scenario, which were used for handoff before. Also, by storing sesion index in vnet_buffer2, we can avoid repeating the lookup after handoff.

This fixes a situation where long-lived inactive session blocks LRU list. Solution is to have multiple LRU lists based on session type.
