It's against drivers/net/intel.c.  The patch is produced by git-diff and 
so includes filename information: you should be able to apply it using just

   git apply ipxe-intel-diag-hack.patch

If you haven't already found the IRC channel (#ipxe on Freenode), then 
give it a try: IRC is quite useful for interactive debugging-at-a-distance.
