Hi Alexey,
We have been working with MIPL to further split the patch as you had suggested. The patch I am sending breaks this into Correspondent Node, Mobile Node and Home Agent functionalities. This patch is against 2.5.45. As part of integrating with 2.5.45 as well as due to the splitting done, there is one outstanding issue with the patch : at module unload time, some memory allocated during module_init is not freed up. However this is a small issue and we are confident of submitting a patch in a couple of days to fix this. The code base is the same that was submitted a few days ago, so the only new thing is the further splitting work and integrating with 2.5.45.
The patch is in two parts, you need to first install the following patch :
http://traci.mipl.mediapoli.com/patches/mipl-2.5.45.patch
After that, please apply the patch at the end of this mail (created as part of 2.5.45 cleanup) to create the final tree. Once the two patches are applied, you will see separate files for the client and the agent parts.
Please let us know if you need any clarification on this patch.
Thanks,
- KK
