Thanks for your reply. It works after above configs added.
It seems all configs which Suriyan specified are needed. Even though
DHCP can be useless depending on the network situation. Sjoerd, How
about add above configs for odroid_xu3.h?
Also, I think it is better to commit this patch separately with my
patchset, because it took too long from when the first patch
submitted, and I really want to make it merged with at least minimum
functionalities.
