Definition

from esp_eth_driver.h:255

esp_err_t esp_eth_update_input_path( esp_eth_handle_t hdl, esp_err_t (*stack_input)(esp_eth_handle_t hdl, uint8_t *buffer, uint32_t length, void *priv), void *priv);

Implemented in esp_eth.c:325

Arguments

Argument

Description

hdl

handle of Ethernet driver

stack_input

function pointer, which does the actual process on incoming packets

priv

private resource, which gets passed to `stack_input` callback without any modification

Return value

- ESP_OK: update input path successfully - ESP_ERR_INVALID_ARG: update input path failed because of some invalid argument - ESP_FAIL: update input path failed because some other error occurred

Notes

After install driver, Ethernet still don't know where to deliver the input buffer. In fact, this API registers a callback function which get invoked when Ethernet received new packets.
