[support] Problems when trying to manipulate the mip6d-nemo-mcoa code

[Angel Bartomeu Bonillo]

Hello,

I installed a piece of code in the movement.c file (some kind of back door)
so I can manipulate some of the behaviour of the Mobile Router from another
software I wrote.
Since I do not know exactly the details of this implementation, I am trying
not to touch the data structures by just trying to fake some events that
lead to what I need the code to do for me.
So far, my code is able to fake the arrival of a Router Advertisement (by
calling the md_recv_ra funtion) so the mip6d register a binding with the HA
and one tunnel is created.
However, I am stuck trying to make the code to expire the binding (which
should lead to the tunnel removal) when I wish.

Basically, what I do now is to call the function "md_expire_coa(iface, coa)"
and then calling "__md_trigger_movement_event(ME_COA_EXPIRED, 0, iface,
coa)"
but thought apparently the CoA is removed from the iface, the binding is
still active in both the Mobile Router and the HA. I also tried to use the
funtion md_free_router(rtr) but, since the default route is removed, no
communication with the HA is possible.

What am I missing? what else should I do to make the Mobile Router code send
the Binding de-registration and deleting the tunnel corresponding to the CoA
I want to stop using?

Thank you in advance.
