Hi,
A Couple of weeks ago I create a patch to add support for DIR-615-D1
https://dev.openwrt.org/ticket/11883
This is to give initial support to that unit. Applying this patch wifi works but still an unknown problem with the Ethernet that still make that unit fail.
You can see more information about our little progress in this tread:

1) I have to redo the same patch 3 times. Can anyone tell me if this patch will be accepted in the future (I mean this century) :-)
2) I am not an expert at all but I can apply patches and build from source so i can verify if this unit works.
