I like this one, but with a twist - the subsystem would have to be more generic
instead of being called 'ibft'.

And it means reworking the ibft driver so that it registers under
this sysfs class and provides the boot data the same way these other
drivers would do. This would also allow multiple iBFT structures
to be exported in case you have multiple NICs - which is something that on the
gPXE mailing list was thrown around.

I think 'iscsi_boot' as a name sounds appealing. Perhaps retain the same
directory structure (that ibft has now) and have the drivers (ibft + other 
drivers) call
such '*_add_target_info', '*_add_nic_info', etc?

True. Would have to change the parent tree. Maybe to to /sys/boot' (or
