Trying to use w5500 as the PHY for Ethernet communication

[imammy-hacomono]

I'm trying to use w5500 as the PHY for Ethernet communication on ESP32.
I tried running the esp_ping command to ping "google.com", but the processing time is unusually long.

I (29363) [Eth]: 64 bytes from 142.250.207.46 icmp_seq=1 ttl=60 time=994 ms
I (30363) [Eth]: 64 bytes from 142.250.207.46 icmp_seq=2 ttl=60 time=999 ms
I (31363) [Eth]: 64 bytes from 142.250.207.46 icmp_seq=3 ttl=60 time=998 ms
I (32363) [Eth]: 64 bytes from 142.250.207.46 icmp_seq=4 ttl=60 time=999 ms
I (32363) [Eth]: 
--- 142.250.207.46 ping statistics ---

I (32363) [Eth]: 4 packets transmitted, 4 received, 0% packet loss, time 3990ms

The output shows that the Ethernet PHY speed is set to 10 Mbps.
Is this affecting the processing time?
Are there any possible reasons for this issue?

I changed the Phy Speed setting with esp_rth_ioctl(), but it seems that the setting value is not reflected even when I read it.
(It remains 10Mbps)
Why is this happening?（disable auto nego）

eth_speed_t speed = ETH_SPEED_100M;
    ret = esp_eth_ioctl(eth_handle_spi, ETH_CMD_S_SPEED, &speed);
    if (ret != ESP_OK) {
        printf("Failed to set Ethernet speed\n");
    }

    eth_speed_t eth_speed;
    ret = esp_eth_ioctl(eth_handle_spi, ETH_CMD_G_SPEED, &eth_speed);
    if (ret == ESP_OK) {
        printf("Ethernet PHY speed: %s\n", eth_speed == ETH_SPEED_100M ? "100 Mbps" : "10 Mbps");
    } else {
        printf("Failed to get Ethernet PHY speed, error = %d\n", ret);
    }
