[lime-dev] Ground routing branch

Hi all! I have just pushed the feature/ground-routing branch to our git repo, the good news is that it is already usable and working, the bad news is that it seems that openwrt doesn't offer a way to know who switch%d is so it could arbitrary be eth0 or eth1 depending on the model and seems there is no way to determine it from software side -_- what I have done now is assume in the code that swtich$i will be mapped to eth$i and although it is not true it works on all device i have and on device we use the most like tl-wdr3x00 what openwrt do is ship a spefic confing for each different device, this config is manually written by the person who write the support for that device so plain old boring manual human work... what we can do is 1) leave stuff as is, so users with "unusual" devices have do do some adjust after lime-config 2) Introduce some kind of very very hardware specific module like the unpopular lime-hwd-tl-wdr3600 we had this summer for each device with a "switch map" readeable by a program 3) Push openwrt developers to implement some kind of mechanism to make switch map readeable from software side
