NAT44: endpoint dependent mode (VPP-1273)
To enable NAT plugin endpoint dependent mode add following to statrup config: nat { endpoint-dependent } Enable endpoint dependent filtering and mapping for all sessions. Move some existing functionality such as service load balancing, twice nat, out2in-only static mappings and unknown protocol dynamic translations, which use endpoint dependent lookup hash tables before. Basically split to vanilla NAT44 and extra features NAT44. Change-Id: I3925eb5ddcc8f1ec4cf6af4e2a618a7ec7aa9735 Signed-off-by: Matus Fabian <matfabia@cisco.com>
