2020-06-08nat: more long read after short write optimizationKlement Sekera1-11/+3
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.

2019-12-04fib: Decouple source from priority and behaviourNeale Ranns1-5/+4
Type: feature the fib_source_t enum alone no longer defines the priority and behaviour, instead each source must be allocated these attributes. This allows the creation of other sources by the plugins (and soon over the API). Signed-off-by: Neale Ranns <nranns@cisco.com> Change-Id: I890ee820fbc16079ee417ea1fbc163192806e853
