OK, so this fails to build on qemu_arm64_lwip (and a few other lwip
targets) because tftpb_run was defined just for the legacy stack and not
lwIP too. But, and this is a question for Jerome too, why isn't dhcp_run
already in the common network file and instead written again in
net/lwip/dhcp.c? And for both of you, can we perhaps have a common
function or functions? The lwIP one does handle tftp it looks like.
Thanks!
