Title:
  move iscsi_ibft and iscsi_boot_sysfs to -virtual kernel

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Calling iscsi ibft a 'virtual' thing is a bit questionable.

  That said, I was looking at ibft using qemu and ipxe.  The cloud
  images do not have the iscsi_ibft module included, so you can't read
  the information out of /sys/firmware/ibft until you have it.

  Given a iscsi target at 192.168.1.131::3260:1:mytest (format is
  described at http://etherboot.org/wiki/sanboot/iscsi_boot)  with a
  cloud image populated (or other bootable data) you can boot from that
  via:

  qemu-system-x86_64 -enable-kvm -m 1024 -curses \
     -kernel /usr/lib/ipxe/ipxe.lkrn  -append 'dhcp && sanboot iscsi:192.168.1.131::3260:1:mytest'

  The ipxe.lkrn file is in the 'ipxe' package, and tested above on wily.

  If the open-iscsi package is installed in the image and the modules
  available, in the initramfs you can then do:

  (initramfs) modprobe iscsi_ibft
  [   11.444414] iBFT detected.
  (initramfs) cat /sys/firmware/ibft/target0/nic-assoc
  0
  (initramfs) cat /sys/firmware/ibft/target0/target-name
  mytest
  (initramfs) cat /sys/firmware/ibft/target0/port
  3260
  (initramfs) cat /sys/firmware/ibft/ethernet0/mac
  52:54:00:12:34:56
  (initramfs) for x in /sys/class/net/*/address; do echo $x; cat $x; done
  /sys/class/net/eth0/address
  52:54:00:12:34:56
  /sys/class/net/lo/address
  00:00:00:00:00:00
