[PATCH 0/6] Add support for MAP MASInstance feature

[Gowtham Anandha Babu]

This patch-set implements MAP 1.2 MAS Instance feature.

The patch 1,2,3 will handle the Client part(MCE). It passes
the PTS 5.3 test case:TC_MCE_MMI_BV_01_I.

The patch 4,5,6 will handle the Server part(MSE). It passes
the PTS 5.3 test case:TC_MSE_MMI_BV_02_I.

My plan is to actually do this as the name of the folder for each instance:

<MAS 1 info>/telecom/...
<MAS 2 info>/telecom/...

If there is no info, due to version or lack of support, then we
fallback to record description or something like that so we can
support multiple instances.

You can drop using mas here since it is pretty obvious what it is for,
also Im not sure we need the size in the callback since we can use
strlen there.

I could not understand the first part of your explanation. 
Do we need to create any folders internally and store the MAS info?
Or do we need to append the below info to MAS Info? 
<MAS 1 info>/telecom/...
<MAS 2 info>/telecom/... 

Let me know if I am wrong. 
And then do we need to follow any predefined structure for storing the MAS Instance Info?
I think right now bluez supports single MAS instance. This patch will work for single instance. For supporting multiple MAS instances, we need to discuss upon the how this can be implemented?

I agree with you. I will update this comment for the patch[6/6] too. I will include this in v2. Still is there anything to be handled?

Start with the server side, I will be working on the client side to
add support for multiple instances, I have something already it just
need some polishing.

I think not much implementation in server side is needed. 
No features are using the instance id in server side except this patch set. But can be added as below:

1)Define no_of_mas_instance (assign no of instances if it supports or '0')
2)While MCE discovering for MAS service, advertise all mas id's(if it supports more than one)
3) While mas_connect(), need to look match for which mas_id the MCE requesting
4) Folder ordering for multiple MAS instance is needed as you suggested. Like
MAS 1/telecom/...
MAS 2/telecom/...

Once the client part is known, we can implement that accordingly. 

Meanwhile is this patch set good to go?
