The dpif-netdev implementation currently invokes offload flow APIs
indirectly through the netdev-offload layer. These calls are tightly
coupled to dpif-netdev logic, but the long-term goal is to have all
offload handling centralized in the dpif-offload-rte_flow
implementation.
To progress toward that goal, we begin by decoupling hardware offload
logic from dpif-netdev and transitioning it into dpif-offload-rte_flow.
As a preparatory step, we replace indirect netdev offload calls with
direct calls. This allows us to clean up the existing netdev-offload
code more easily and isolate remaining dependencies.
This patch does not complete the transition but sets the foundation for
a cleaner separation between the datapath interface and offload
infrastructure.
