2020-04-24nat: ignore user hash in ED NATKlement Sekera8-362/+273
With port overloading, port is no longer a scarce resource and there is no need to limit connections per internal IP. This saves one hash insert in slow path. Type: improvement Change-Id: I8a7a9713ac855fa99fa1617ec684f757cf6e09ae Signed-off-by: Klement Sekera <ksekera@cisco.com>

2020-04-24tests: test vnet_calc_checksums_inline(...)Dave Barach1-0/+74
Use a hand-crafted packet generator script to inject packets with deliberately broken ip4 and udp checksums - and the appropriate checksum offload flags - into src/vnet/interface_output.c vnet_interface_output_node_inline(...), and make sure that the resulting checksums are correct. Use the packet tracer to catch one of the packets. Parse through the packet trace, and make sure that the checksums have been correctly computed.

2020-04-24nat: ED: reduce number of hash tables usedKlement Sekera5-212/+210

Adapt queue_hi_thresh value using num_threads to avoid risk of deadlock between threads which could happen for example when different NAT threads try to handoff work to each other at the same time when their frame queues are congested.
