ESP32 以太网：如何获取当前链路速度

这是你如何使用 ESP-IDF 框架在 ESP32 上获取以太网连接的当前链路速度。

esp_eth_get_speed.cpp

#include <esp_eth.h>

// 获取链路速度
eth_speed_t link_speed;
if (esp_eth_ioctl(eth_handle, ETH_CMD_G_SPEED, &link_speed) == ESP_OK) {
    const char* speed_str = (link_speed == ETH_SPEED_10M) ? "10 Mbps" :
                          (link_speed == ETH_SPEED_100M) ? "100 Mbps" : "1000 Mbps";
    ESP_LOGI(TAG, "Ethernet Speed: %s", speed_str);
}

#include <esp_eth.h>

// 获取链路速度
eth_speed_t link_speed;
if (esp_eth_ioctl(eth_handle, ETH_CMD_G_SPEED, &link_speed) == ESP_OK) {
    const char* speed_str = (link_speed == ETH_SPEED_10M) ? "10 Mbps" :
                          (link_speed == ETH_SPEED_100M) ? "100 Mbps" : "1000 Mbps";
    ESP_LOGI(TAG, "Ethernet Speed: %s", speed_str);
}
