Kirkwood! It has been a while since we had a kirkwood patch. Some NAS
boxes seem to never die. Nice to see somebody still hacking on them.

Netgear firmware only supported SMBv1, Windows 10 does not. Luckily
Arnaud Ebalard had done most of the heavy lifting years ago. Getting
the LCD working with the new HD44780 driver was icing on the cake.
Thanks,
