Add Kconfig symbol LWIP_ICMP_SHOW_UNREACH which, when enabled, prints a message to the console upon reception of ICMP unreachable messages. For example: $ make qemu_arm64_lwip_defconfig $ qemu-system-aarch64 -M virt -cpu max -nographic -bios u-boot.bin [...] => dhcp DHCP client bound to address 10.0.2.15 (0 ms) => tftp 192.168.0.100:69:Image Using virtio-net#32 device TFTP from server 192.168.0.100; our IP address is 10.0.2.15 Filename 'Image'. Load address: 0x40200000 Loading: ICMP destination unreachable (host unreachable) from 192.168.0.16 Timeout! => tftp 192.168.0.16:69:Image Using virtio-net#32 device TFTP from server 192.168.0.16; our IP address is 10.0.2.15 Filename 'Image'. Load address: 0x40200000 Loading: ICMP destination unreachable (port unreachable) from 192.168.0.16 Timeout! => Submitted upstream as https://github.com/lwip-tcpip/lwip/pull/73.

Lower values result in slower wget transfer speeds in

general, especially when the latency on the network is high,

but QEMU with "-net user" needs no more than a few KB or the
|
|
transfer will stall and eventually time out.
