rS314948: Try to extract the RFC1048 data from PXE. If we get enough info we can skip
Summary

Try to extract the RFC1048 data from PXE. If we get enough info we can skip the bootp().
It removes unnecessary DHCP request from pxeloader.

I'm not sure if it should be a default, maybe somebody wants to give a different answer from DHCP, depends on stage of netboot on the same machine.

Is this needed as it looks like its to ensure its only included once by the _BOOTP_H_ should achieve that

The formatting here is a bit odd, remove the "." ?

Should this only be output under verbose boot or pxe_debug?

Didn't spot this before but does this need a more explicit test as this method returns and isn't not a book and it's not clear what's the -1 is meant to trigger and how it's dealt with here?

book -> bool
