svn commit: r200310 - in head/sys/boot/i386: gptboot zfsboot

New Revision: 200310
URL: http://svn.freebsd.org/changeset/base/200310

Log:
  Fix a confusing typo in the EDD packet structure used in gptboot and
  gptzfsboot.  I got the segment and offset fields reversed in the structure,
  but I also succeeded in crossing the assignments so the actual EDD packet
  ended up correct.
