ip stack mutual exclusion

[Fermi at aol.com]

In the documentation you talk about a network-task, an interface receive task and possibly a user task (depending on implimentation) accesing data structures 
that are ip-stack resident and ensuring consistancy by acquiring a mutex. 

The Security Association database I spoke of can 
be manipulated/accessed from within the context of
a user task(ISAKMPD)and the network task.

I will have to take care that my user task(ISAKMPD) 
acquires that semaphore via calls to rtems_bsdnet_semaphore_obtain/release()?
