> The commit [1] ("northd: Add support for stateless ACLs with load balancers")
> incorrectly handled connection tracking when enable-stateless-acl-with-lb is
> enabled,
> causing all stateless traffic in egress to be committed to conntrack.
>
> This fix properly implements the enable-stateless-acl-with-lb behavior by:
> When enable-stateless-acl-with-lb is enabled:
> - Still sending stateless traffic through connection tracker lookup
> in egress.
> - Adding new flow in ls_out_stateful to skip committing NEW stateless
> connections.
> - Only committing established connections for proper return traffic
> handling.
