My goal was to do that in the next version of this patch. My first step was
to get the fundamental work reviewed (and hopefully accepted) and then build 
on top of that.

The exploiter of this binary file (/sys/firmware/ibft/table) is the 
iscsi-initiator-utils package and it has a library that parses the binary 
blob data. The thought was to get this first working (ie, 
iscsi-initiator-utils finds /sys/firmware/ibft/table, parses it and work) and 
then work to have the iscsi-initiator-support individual sysfs entries.

Or do you think I should skip the fundamental step and work on the next
version of this patch that exports the data as individual data and post that
one instead?
