HP 2570p (no network with iPXE undionly.kpxe) but ipxe.lkrn is working.

Torgeir: yeah, the reason that patch is not included in the mainline is because it is a hack that uses a hard-coded identifier to make an exception, something which is generally frowned upon to solve a problem that is supposed to be generically solved. But I believe the problem is actually in the firmware and need to be fixed by the vendor for iPXE to work. I seem to recall it is about the hardware telling outside code that it uses interrupts for communication, but doesn't actually generate any interrupts at all.
