[Chilli] Period "Reauthorisation"

[Tim White]

Thanks Royce. I wasn't aware of CoA.
If I understand this correctly, with accounting updates chilli sends a 
CoA packet (if coaport is defined). However, some googleing also shows 
acctupdate. I'm using FreeRadius, and some of the documentation in the 
old Coova Wiki seems to be gone.
Any idea which is the better one to do? CoA or acctupdate? Do they both 
work for updating the remaining data/time or is CoA just for disconnects?
Normally I can find most things with Google, however this topic is 
eluding me. Having the right search terms is helping now, but there 
seems to be a lack of documentation.

Thanks

Tim
