This code (partially done) is basically new. I used many other implementations
for reference including the freeable Mt.Xinu code. The netboot that I
supplied uses the added support in the /sys/lib/libsa (created from libnetboot)
and a new boot filesystem - nfs.c . The polled driver is from Adam's sun3
lance driver with changes to work on the 300.

The status of the code -

- gets info via bootp request ok
- can read a simple file via nfs

The test driver - netboot.c did this. There is a generic exec.c in libsa
that now should be used. One open issue was how to locate the swap server,
and then patch the memory of the loaded image, but this was solved by the
new diskless support. Basically don't bother the kernel will figure this
out using rpc.bootparam (or what ever) when it boots.
