NetIF_Add()

Add a network device and hardware as a network interface.

Files

net_if.h/net_if.c

Prototype

Arguments

if_api

Pointer to the desired link-layer API for this network interface and device hardware. The desired link-layer interface will point to the Ethernet API (NetIF_API_Ether) or the WiFi API, (NetIF_API_WiFi).

dev_api

Pointer to the desired device driver API for this network interface.

dev_bsp

Pointer to the specific device's BSP interface for this network interface (see also section Network Board Support Package).

dev_cfg

Pointer to a configuration structure used to configure the device hardware for the specific network interface (see also section Network Interface Configuration).

ext_api

Pointer to specific network extension layer API.

ext_cfg

Pointer to specific network extension layer configuration.

p_err

Pointer to variable that will receive the return error code from this function:

NET_IF_ERR_NONE
NET_IF_ERR_NULL_PTR
NET_IF_ERR_INVALID_IF
NET_IF_ERR_INVALID_CFG
NET_IF_ERR_NONE_AVAIL
NET_BUF_ERR_POOL_INIT
NET_BUF_ERR_INVALID_POOL_TYPE
NET_BUF_ERR_INVALID_POOL_ADDR
NET_BUF_ERR_INVALID_POOL_SIZE
NET_BUF_ERR_INVALID_POOL_QTY
NET_BUF_ERR_INVALID_SIZE
NET_OS_ERR_INIT_DEV_TX_RDY
NET_OS_ERR_INIT_DEV_TX_RDY_NAME
NET_ERR_FAULT_LOCK_ACQUIRE

Returned Value

Network interface number, if device and hardware successfully added;

NET_IF_NBR_NONE, otherwise.

Required Configuration

None.

Notes / Warnings

The first network interface added and started is the default interface used for all default communication.

When a PHY layer is present, the PHY API and configuration need to be indicate in the ext_api and ext_cfg arguments.

Additional error codes may be returned by the specific interface or device driver.

See section Initializing Interfaces for a detailed example of how to add an interface.
