net/mlx5e: CT: Offload connections with hardware steering rules
This is modeled similar to how software steering works:
- a reference-counted matcher is maintained for each
combination of nat/no_nat x ipv4/ipv6 x tcp/udp/gre.
- adding a rule involves finding+referencing or creating a corresponding
matcher, then actually adding a rule.
- updating rules is implemented using the bwc_rule update API, which can
change a rule's actions without touching the match value.
By using a T-Rex traffic generator to initiate multi-million UDP flows
per second, a kernel running with these patches on the RX side was able
to offload ~600K flows per second, which is about ~7x larger than what
software steering could do on the same hardware (256-thread AMD EPYC,
512 GB RAM, ConnectX-7 b2b).
