Yes. I have pings working in IDF version 5.2.1
I had to use a different ping code.

Here is my thread discussing it.

Awesome. That worked. Thank you. If I wanted to take an existing port after being initialized as a non server port, is there a way I can reinitialize it as a DHCP Server port without rebooting? I can stop the state machine (down the port) but I don't see a way to unattach the glue and do a new confi...

I am using IDF version 5.2.1 and an ESP32-WROOM module. I have a KSZ8863 3 port switch that provides two Ethernet ports (using 2 port mode). Everything is working well sending packets through the TAP interfaces. ARP, ICMP, UDP packet flow all as expected. Now I want to take one port and make it an i...

Just figured out a solution.
If I stop and start the interface after enabling the DHCP process, it grabs the DHCP address and everything works.

I am using a KSZ8863 and L2Tap functions. IDF 5.2.1 with ESP32S3-WROOM module. I am able to boot up and use DHCP as the default. I am also able to switch to Static IP by disabling the dhcpc function and setting the IP. The problem I have is when I try to go back to DHCP. How should I do that? Do I j...

You can use the etharp_get_entry() function. Something like this: struct eth_addr *ethaddr; struct netif *netif; struct eth_addr *ea; for( int i=0;i<ARP_TABLE_SIZE;i++ ) { int ret = etharp_get_entry(i,&ipaddr,&netif,&ea); if( ret ) { // print contents of IP (ipaddress->addr), interface (netif->num),...

I put in a log statement and see lots of buffers that need to be freed.
So I guess I need to identify my packets that don't need to be freed or I need to allocate a buffer that can be freed (preferred).

I found a work around but not sure if it is complete. When calling eth_netif_receive() it wants to free the buffer, but my buffer is static and doesn't need to be freed. I created my own empty function and assigned it to myNetif->driver_free_rx_buffer to override the default. Now the pings work and ...

Once you open tap interface for specific ethertype, these frames are then only accepted by the tap interface. They are not passed to the IP stack. It's described at: https://docs.espressif.com/projects/esp-idf/en/stable/esp32/api-reference/network/esp_netif.html#e-esp-netif-l2-tap-interface Please ...
