[Commotion-dev] adding Babel + IPv6 support - follow-up 2

[Linic]

Hi,

BABEL + IPv6
------------------
We created a first branch which we'll turn into a pull-request today. It 
contains the work we have done with Babel and IPv6. When Babel is turned 
on, Olsr is turned off and IPv6 unique-local addresses are configured on 
the Lan interface. The mesh interfaces use the link-local addresses.

How to turn on Babel in this pull-request :
1) uci set network.<meshName>.proto=babel  (meshName is the value of 
'uci show wireless.commotionMesh.network')
2) uci set wireless.commotionMesh.proto=babel
3) uci commit
4) /etc/init.d/network restart

The branch for the pull-request is here : 
https://github.com/reseaulibre-polymtl/commotion-router/tree/babel. You 
can test the changes with an image we built here : 
http://serveur1.lerb.polymtl.ca:8080/job/commotion-router-polymtl/4/.


Web interface
--------------------
The changes we made to the web interface are located here : 
https://github.com/reseaulibre-polymtl/luci-commotion/tree/babel. We 
would like to know if you prefer to have a look at it before we make a 
pull-request or if you prefer to receive a pull-request right now.

Changes made to the luci-commotion web interface:
1) Basic status pages: when the selected mesh protocol is babel, a 
warning is shown instead of olsrd daemon errors.
2) Add mesh protocol selection to basic mesh configuration and setup wizard.
3) Add babel protocol to advanced network interface protocol selection.
