net: lwip: add Kconfig option to show ICMP unreachable errors
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
[...]
