[Per Kristian Hove, 2003-09-24]
| When netbooting, the sparc64 loader tries to download the kernel from
| the wrong server address.
On further investigation, the cure is quite trivial (and not sparc64-
specific). The attached patch to /sys/boot/common/dev_net.c fixes this
problem.
Should I open a PR?
