npr::rf::NprNetworkBridge class final
#include <npr/runtime/network_bridge.hpp>

NPR-to-generic networking bridge used by shared network task runner.

Base classes

class prf::net::IPrimaryNetifConfigProvider
Provides the primary routed IPv4 interface snapshot consumed by the network stack.
class prf::net::Ipv4LinkAdapter

Constructors, destructors, conversion operators

NprNetworkBridge(NprRuntime& runtime) explicit
Binds bridge to NPR runtime instance that owns queueing and network config.

Public functions

auto dequeue_downlink_ipv4(uint8_t* out, size_t out_capacity, size_t* out_size) -> bool override
Dequeues IPv4 downlink packet from NPR towards lwIP input path.
auto enqueue_uplink_ipv4(const uint8_t* packet, size_t packet_size) -> bool override
Enqueues IPv4 uplink packet from lwIP towards NPR uplink queue.
auto mtu_bytes() const -> size_t override
Returns NPR IPv4 MTU supported by frame segmenter.
void set_npr_config(const npr::cfg::NprConfigSection* npr_config)
Deprecated no-op retained for compatibility with existing runtime wiring.
auto snapshot_primary_ipv4_config(prf::net::Ipv4NetifConfig* netif_cfg) -> bool override
Collects current NPR role-specific routed netif snapshot.

Function documentation

npr::rf::NprNetworkBridge::NprNetworkBridge(NprRuntime& runtime) explicit

Binds bridge to NPR runtime instance that owns queueing and network config.

Parameters
runtime NPR runtime instance.

bool npr::rf::NprNetworkBridge::dequeue_downlink_ipv4(uint8_t* out, size_t out_capacity, size_t* out_size) override

Dequeues IPv4 downlink packet from NPR towards lwIP input path.

Returns true when a packet was produced.

bool npr::rf::NprNetworkBridge::enqueue_uplink_ipv4(const uint8_t* packet, size_t packet_size) override

Enqueues IPv4 uplink packet from lwIP towards NPR uplink queue.

Returns true when packet was accepted for transmission.

bool npr::rf::NprNetworkBridge::snapshot_primary_ipv4_config(prf::net::Ipv4NetifConfig* netif_cfg) override

Collects current NPR role-specific routed netif snapshot.

Parameters
netif_cfg Output npX/lwIP netif configuration.
Returns true when NPR runtime has valid network config.

Today this consumes slave-learned CONNECT_ACK state. Future master mode sources netif settings from local NPR config while still keeping host-side service interfaces outside src/npr.
