Hi @lumag nice! Nothing to thanks!

@quaresmajose Thanks you all for the reviews and comments. @calebccff Can't wait to see eth support at u-boot level and weston.

If I have some time I will try to take look on that into the next months ;)

ethernet works nicely on the rb1/2/5, its unfortunate that the rb3 and rb3gen2 use pcie hubs, but I'm working on it :p
