Please don't repost the same issue with a different name... Check your driver code, from what the other user said, looks like non-IP packets are being discarded without freeing their buffer. Check with the one who wrote the driver and/or the port.
When the Ethernet controller signals frame(s) pending, the receiving task allocates a buffer for it and transfers data. Then, this buffer is checked for upper-layer protocol and handled to the stack or discarded. Code for this is in the netif tree and is modified by the one providing the driver and the port. _______________________________________________ lwip-users mailing list lwip-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/lwip-users
