Bug#537502: missing ethernet firmware is forgotten about

[Petter Reinholdtsen <pere@hungry.com>]

With my latest PXE installation testing on a laptop, I ran into a
problem I suspect is related to this fix:

   [ Joey Hess ]
   * check-missing-firmware: When called from ethdetect, take interfaces
     up and down each time through the loop. Previously this was only done
     once, which caused a bug, as the first pass through does not prompt
     for missing firmware, and on subsequent passes, the firmware was not
     requested. Closes: #537502
     (Thanks, Asbjørn Sloth Tønnesen)

When testing PXE on a HP Mini laptop, the PXE installer starts
normally, is able to download udebs and continue to the point where
partman try to download more packages.  At this point 'route' report
there is no longer any routes set up, and connections to the mirror
fails.  I looked in the syslog, and hw-detect was running just before
partman started, making me suspect it is the cause of this problem.

Happy hacking,
