This simple patch makes the DHCP/BOOTP/RARP code sleep with schedule_timeout() instead of hogging the cpu with cpu_relax() in a loop. This comes handy when a guest kernel is booted inside QEMU. Without the patch, the host operating system will consume cpu time busy waiting.
There are two similar loops involving CONF_PRE_OPEN and CONF_POST_OPEN, you may wish to hit those while you're at it.
